I didn't think that was out of the ordinary for MC to talk about...I'm just learning about motorcycles and I found MCgarage to be very informative. I have learned quite a bit from this show, I love it. I also like how it's not a 30min long lecture, it interests me through the whole video, but doesn't waste my day away...I definitely learned a few things from this video. Well done guys. Keep it up! Cheers!
I'm a long term rider and never heard this answer before. I learned something new and I love learning about riding and I love the MC commute vlogs too. I'm a serious driver and decent backyard mechanic, but not too familiar with the motorcycle physics,dynamics or other parts. I just ride because I love to and use my lil 600 Bandit as a commuter here in NorCal.
This was my exact experience at the track lately. I ride a Yamaha R3, and the tire vendor didn't have my size, but suggested I try a larger: 110 to 120, and 140 to 165 (the smallest they had), and I lost about 50% of cornering performance, and the bike felt like it leaned another 10 degrees without trying - I had to lean even more to corner and the exhaust started dragging
Maybe you ought to make a video, cause I can see that R1 is sporting some rather wide and shiny chicken strips, while talking to us about tires. Tire width has more to do with tire curvature profile, target temperature, heat dissipation, while maintaining proper rotating mass as it relates to gyroscopic precession... than overall width, contact patch, and ultimately looks.
Interesting, this is the exact situation I'm in. Just bought an R3 and the former owner had a 120 front and 160 rear on it. Looking forward to wearing them out so I can go back to 110 140.
@@bradtidball I hope you get through them fast. I had a tough time - I kept running off the track because I wasn't used to the decreased turning. I do admit it was a good learning experience - and the first time I drug my knees lol.
@@michaelwatkins8871 Interesting. It's all I've known on this bike, so I don't have a different point of reference like you do. Still have a few thousand on these tires unfortunately.
@@bradtidball You might miss the lean angle lol. I recommend the Dunlop Q3+ for the R3. It's very sticky for a street/track tire. I once parked the bike on a painted concrete surface after riding on the street, and the paint peeled off when I moved the bike. It used to be the MotoAmerica race tire selection for that class of bike.
ADV bikes have the skinny tires so that they can pierce mud, snow, dirt and the like. That way they can "plow" things to the side instead of pushing it forward or hydroplaning. I really enjoy your MC Garage videos. I wish you guys could do more of them.
giff74 Also larger diameter wheels and tires offer better off-road handling and overall performance when the pavement ends. As with the reasons you mentioned, it is why the new Africa Twin uses 21"front and 18" rear, just like every non motocross, off road racing dirt bike uses. A 21" front wheel has an easier time going over rocks, roots and other obstacles. Think about a skate board wheel and how easily it gets locked up on small tiny rocks but say a shopping cart wheel will go right over that same tiny rock. The larger wheels and tires also offer better stability off-road. Think about pit bikes and how some pit bike racing classes are based off the size of the front tire. Those with say a 10" front wheel are much less stable than those with a 12" front wheel.
Nah, cause most ADV riders are skinner than the average cruiser rider, that is why they don't need fat tires, cruiser rider are mostly morbidly obese so they need fatter tires :D not exact science but base on observation :D
Another great video! Thats what many people like to do here in Indonesia, they use 190/55 on a Ninja 250 or Yamaha R25 (in Indonesia is 250cc version, not like Ninja 300 or Yamaha R3). They just swap the tire rims with the wider one, like 5.5" wide and use that big wide tires over a quarter litre engine. Mostly, people use 160/60 on the rear wheels on a stock rims, 4" wide. I guess they just want to look great with the wider tires, instead of having a good performance on their bikes. I completely agree with what you explained in the video, and I learn something new!
WicakSOUNDno Thanks for sharing bro, i didn't know they could fit such a huge tyre on 250s! I plan to replace a 150 size over the stock 140, do u think it's suitable? Or would it compromise the handling too much? So many people tell me it would improve corner grip, i just need to be sure.
gronkgrunk But of course they changed the arms also, usually they install arms from bigger bikes, Its suitable just fine I believe, I ride Yamaha R25 on the front 120/60 and 160/60 on the rear. I guess for the corner grip is depending on what kind of tires that you are using, either soft, medium, or hard compound, and how confident when you are taking a corner with your bike and stock tires.
I put a 150 on my CBR250's 140 rear. Not for looks or performance or whatever but because the Michelin Road Pilots only come in 150 and larger and those are the only tyres I would ever want on my commuting bike. Bike felt like it wanted to drop into a lean more quickly due to steeper profile but no clearance issues or any issues for that matter. As for performance... a much wider tyre on 250/300 will only hinder performance. Bike doesn't have enough power or weight to need the extra grip and will only have to accelerate a heavier weight.
Another interesting thing about tires and lean angles is that when you lean, because the tire is curved you essentially decrease its radius and essentially lower the gear ratio causing the bike to increase engine RPM relative to speed.
Wow great segment on tires! I've been and still am a tire technician for just over twenty years and Im impressed with how accurately you explain the many different types and uses of tires. Especially proper inflation. Love watching your videos good job guys👌👊
This is actually the sort of discussion I was hoping MC garage would go into when I found the series, really looking forwards to continuing. ADV bikes have skinnier tires to focus their weight onto a smaller area on the ground and increase traction.
Great video.. there's a guy at Cycle Gear actually tried to talk me into putting a 190 tire on my rim that usually has a 180 on my FZ1... he said it didn't matter people do it all the time.. thanks to videos like this one I went back with the proper tire size.. just goes to show just because bikers work at Cycle Gear doesn't mean they actually know their stuff...
Well it will keep up with one in the corners no problem. Infact I've seen Mt 07's beat R6's round corners, whilst obviously the R6 left them in the dust on the straights
Talk about tyres such as this vid don't get nearly as much attention as they deserve. After all, it's arguably the most important safety aspect of any bike. Good and correct tyres = less risk. This vid was a great education. Thankyou! 👍
I'm not a motorcyclist but I'm sure you guys will always appreciate some feedback. I only clicked on the video cause it was an interesting question. Super professional video! Love how you didn't get arrogant or throwing around gangster signs and didn't swear - I feel like a lot of MC channels have fallen into that hole. Keep up the good work!
My guess... Because wide tires are like sleds and narrow tires are like ice skates- control. Plus the center of gravity issue form the vid. Off road, lean angle looks like trouble.
That last question is exactly what I was looking for the answer. Ehehe. I do own a Honda NC 750x, and comparing rim sizes with the Africa Twin, realized that the second one has more narrow tires but bigger wheels. Interesting to know what that sizes improves offroad handling. Please do continue with your awesome videos. Cheers from the Azores Islands - Portugal.
I ride big adv bikes (honda varadero 1000) and we use narrow tires because is more heasy to handle this kind of heavy bikes, also, we don't need to lean as much as a sport bike to make fast corners (not as fast as a sport, but still fast), and also with a wide bag setup, we can also lean a lot or we will be scraping the crap out of the bags...
Good explanation on the matter and you're absolutely spot on. I was doing a track day with a local club in NORCAL and had a 2017 R1 running 190's. I couldn't believe how much I had to lean her over to get through the same turn compared with 2000 Ducati 996 SPS running 180's. Later that afternoon we installed 170's and the bike felt more nimble even less lean angle and still knee down on the Mazda turn at BW watching a Super Duke with two up videoing me as it was passing with less lean almost straight up on the turn!!! Always got spanked around the corners by the 250 cc class who never used brakes before entering and through the corners. Your realize quick how vastly different performance is with different bikes, different tires, and different setups and how it is different at different points on the track.
Can't agree more with this. The factors you mentioned are all spot on. Also, manufacturers (at least here in Indonesia)actually suggest "tolerance level" for various rim sizes if owners are not satisfied with the stock tires (though to be frank, the suggested sizes are just one size up or down as you have mentioned ). As a side note, I was often asked the difference between U-shape profile tires and V-shaped profile tires. All I can say is that these refer to the tires' tread shape when they are installed on the rims and that U shape tires give better stability on tight turns while V-shape tires are good for long corners with the same tire size. It would be a most welcome if you guys have better explanation for this and share it here. I really love watching MC Garage videos. It's very informative and inspiring. I hope you guys keep on making them.
I'm a long term rider and never heard this answer before. I learned something new and I love learning about riding and I love the MC commute vlogs too.

Interesting! I presume the narrower tyres on ADV bikes are to cut through soft mud to get traction on more stable ground beneath as opposed to a wide tyre just floating on the mud?
Maybe the leaning and weight; ADV's already weigh alot so shedding weight from the tire might help. And as he said in the video, narrower tires don't have to lean as much
I know from my experience with tractors. We often fit narrower tires for some types of muddy/ hilly conditions. It is true that wider tires cant get grip on loose or slippy surfaces. while a narrower tire with the weight of the vehicle acting on it bites in and grips much better. That said. In really deep mud. a narrow tire can have you stuck up to your axles so in that case you might opt for a wider tire to help you float better.
I had an YAMAHA RD LC 125 EIDS(ENERGY INDUCTION SYSTEM) PRE YPVS in the 80`s and used a MICRON POWER EXHAUST/UPGRADED THE AIR FILTER TO A POD METAL MESH! K``n `N POD FILTER(this sucked in water when the weather in blighty/GB was wet:( I had BOYSEN RACING REEDS and NGK RACING PLUGS, plus I upped the main jet and raised the throttle lift circlip to corrisponde/COPE with the extra fuel and I kept the tyres sizes standard at first but played around with the compound by buying metzelers BUT upped the front to a size bigger and had a standard size rear. The outcome was a extra 10 hp and a 5 mpg more thirsty beast to begin with. But it was genuinely faster and harder to turn into bends at first but it did hold the line better at top speed of 80 mph and also stopped the bike from wandering on the straights:) My conclusion is fatter tyres give the bike more stability in a straight line but make the bike harder to turn:) PPS I had a FORD XR2i (FORD FIESTA) and put widder pepperpot wheels on it and when it snowed they were SHIT*:( I put narrow tyres on it and they were as you would have guessed brilliant.
One of my favorite channels, basics well explained. I was surprised, when I had the chance to test ride a Yamaha FZ-07 today. It has a 180 rear tire but handles pretty good though.
Absolutely love MC Garage videos, you guys rock, especially Ari. ADV bikes aren't designed for high grip situations, they need lower mass tires to facilitate navigating (pushing) through different terrain.
I am going to have to agree. I only weigh 155lb and the advantages far outweigh the disadvantages, such as braking. I also think to turn well, it is your technique and timing more than your tire size; however, different strokes for different folks. If you have a 250 or 300, it is obnoxious to go up to a 190. To swap the rim means you are taking something from somewhere else. I am not saying you will like or dislike it, I am saying it has to come from somewhere else.
thanks for stepping up the technical details and accuracy in this tire overview. much, much better than the radial vs axial break technical overview. keep up the good work.
I switched the stock 140/70 tires on my ninja 300 to 150/60 Bridgestone battlax tires and would never go back. Yes a little bit of me wanted a fatter back tire but the really reason I wanted to switch was for stability. The 300 was way to flickable! The damn thing was hard to hold in a line going around corners, it didn't have a very planted feeling at all. The wider tire makes a noticeable difference without wasting money on silly upgrades such as suspension and steering dampeners. I decided to go for 60 mm aspect ratio simply because it made the least amount of difference on the overall circumference, thus no need for a speedohealer. Not to mention that the stock tires were awful, more than glad I decided to switch!
Aditya Mohan Both the stock IRC tire and stock dimensions Kawasaki chose to be honest. I noticed that the IRCs lacked grip. Specifically, the rear wheel tended to slip during hard breaking and quick launches. In terms of performance, the bike rides better overall, mainly during curves like explained before. The battlax tires provide a lot more grip, in fact I am not afraid to lean in as far as possible with them. I'm not sure if the new tires weigh more. If they do, the power loss isn't very noticeable. In my opinion, the bike was far too wobbly while leaning in with the stock tires.
I was thinking of doing the same switch on my R3. The stock tires are horrific, and every time I do research anyone who did the switch said they immediately felt a difference in overall feel of the bike. They also felt more confident as well. And MC Garage here also said the Bridgestone S21(battlax) are the way to go for a nice performance boost. Out here in new york tho, and it's stored away for the winter. I gotta wait until mid march to do anything T_T
But wait, isn't grip (friction) dependent on the force pushing the two materials together, in this case the tire and the road, and not their surface area? As in, shouldn't two tires with the same weight but different contact patches, still offer the same grip? Obviously big tires are fitted on bigger, heavier bikes, but does the increased contact patch really offer more grip by itself?
@Austin Yount, it's rather more complicated than your formula makes out. That's the formula they give in early physics classes, but the reality is a bit more complicated than that. The area of the contact patch definitely does make a difference, otherwise people wouldn't underinflate their tires in order to gain traction. It's still the same material, but it's warmer, wider and stickier than a more inflated tire would be. As for centrifugal force, nope, sorry, he didn't say that. He said centripetal force, which I took note of as it's so rare for these videos to bother getting that right.
Chris L I know it's much more complicated than that. After all, the formula for force of friction is well known to be only an approximation as with pretty much all classical/Newtonian physics. If we knew everything, we wouldn't be relying on approximations but we don't know everything and our approximations are extremely accurate. So accurate in fact that the engineers who designed the cars and the tires used these same approximations in their design process. I think that contact patch is important as well but it doesn't really seem like anyone knows exactly why. You do bring up an interesting point in regards to underinflation. My hypothesis would be that an underinflated tire flexes and bends more causing it to heat up and get stickier as you said but what does stickier mean? Stickier actually means that we've changed the coefficient of friction. the same piece of rubber will have a higher coefficient of friction when it's hot. I would also think that a wider tire or underinflated tire would be better at coping with road irregularities like pebbles for instance because it is more likely to have another part of the contact patch pressing on stable ground. remember these are all just ideas. No one has been able to answer this question that I'm aware of. As for him using the word "centrifugal" vs "centripetal" force, I've listened to him say it multiple times and my ear hears "centrifugal force" every time. But it really doesn't matter in this case because he goes on to talk about "the force pushing to the outside of the turn" which we both know is practically the dictionary definition of the mythical "centrifugal force". So either he stated the correct force while completely misunderstanding the physics involved or he stated the mythical force while still completely misunderstanding the physics involved. The two words are not interchangeable. Whichever way you cut it, he's still wrong.
*in regard to ... (no regard(s)). Regards(s) indicate good wishes or respect as opposed to the singular 'in reference to.'*as regarding ...*as it regards ...Better yet ... 'concerning'
Grip is not equivalent to friction. Friction works as you described, but grip has more components than just friction. Tires are made of a softish compound because that allows it to "grip" onto a rugged surface, such as asphalt, and the bigger the contact patch, the bigger the surface that can interlock.
Why do you think centrifugal force is "mythical" or "imaginary"? It's just a force that exists in the rotating non-inertial reference frame. As far as the moving motorcycle is concerned it is a very real force.
Great info. I was doing a lot of googling about installing a fat rear tire on my Honda Shadow, but after watching this video I think I'll stick to my stock 170/80-15.
I have a 2009 honda shadow. The speedometer was way off. About 10mph. I put the next size up tire on the back years ago and it’s way closer to actually speed along with zero real world handling draw backs I can tell.
I really enjoyed this. I have been thinking about changing the width on my street triple from a taller 180 to a lower 190 for the looks, but didn't wanted to compromise acceleration. I'll probably stick to 180 though. Didn't know the difference and characteristics of the lean angles between them. Now it makes total sense why I feel that I lean much more on my diavel with a 240 than the triple with a 180. Thank you very much and keep up the good work!
Ari Henning, please also review why all bikes are handled by default from the left side and not on the right. I just thought about it. Anything from the right feels uncomfortable. Thanks and your reviews rock!!
When you're cornering, accelerating, braking,.... tires are doing work. But rubber's work isn't 100% efficient and that's what's causing wear and heating (and tire drag or rolling resistance). The wear is caused by rubber going out of the tire due to friction. The more the tire is gripping the road texture (due to pressure), the more you have grip (you can even go above 1.0 coefficient of friction with good tires and good conditions). But if it stressed (pressured) too much, the rubber in contact with the road will just tear appart before it was able to do all its work and you're losing grip. In conclusion more surface (wider tire) DOES NOT equals more grip. There's an equilibrium point between "rubber deformation gripping road texture =>|
Fun fact : In the efficiency races (1 galon gas races, etc...) they don't bother that much about grip but energy waste is a big deal! In these kind of races they prefer super hard compound and super thin tires. It is more aerodynamic, it causes less rolling resistance or tire drag and it lasts longer! In regards of energy efficiency, wide soft tires are a nightmare. There is never "always good" or "always bad" features, wether a thing is good or bad always depends on what you're looking for.
That's a great video Ari .. I've gone through the gambit of trying to run wider tires on my bike for the last year and came back to the exact mentality, stock was best for a reason - I corner and accelerate much better on skinnier treads .. Wish you'd have made this last spring hahaha ..
Generally, the wider the tire, the more rolling resistance it will have. This can have a very significant effect on something like a bicycle, but on a motorcycle, I doubt you would even notice it.
Something very important to consider when choosing what tire to put on a bike 300ccm or less is the friction. Wider tire causes more friction, it makes very small difference when accelerating, but it can change the top speed by a lot, so if you are doing a lot of motorway riding, make sure the wider tire doesn't put you below your cruising speed.
wider = better grip/better stabil, harder for turn/manuver, slower/more power loss narrower = less grip/less stabil, easier for turn/manuver, faster/less power loss thicker : less grip/less downforce, faster thiner : more grip/more downforce, slower
@@lanchanoinguyen2914 yeah. Actually faster in cornering. That's why 300cc and 600cc will beat a 1000cc in twisties. Smaller the tire, the better the handling. Example: a Toyota Supra can beat a Dodge Charger in twisties because of less weight.
My 2015 BMW 1200GS has the 170 on the rear and its probably the best road handling bike I have ever ridden and Ive ridden a lot including sports bikes super nakeds etc. The GS's handling is sublime
Width relationship between front and rear is another hugh consideration towards expected behavior. Studying the history of the Yamaha SX 650 changing the rear from 18 to 16 as well the Honda 750K verse the 750Four 16 to 18.
sir your every video contains knowledge which in general people do not talk , thanks for sharing such information with us... awesome videos by the way.
id prefer to roll with the original tires nomatter what and I don't know about mc garage but I personally think that having a wider tire than what is prescribed for your bike that it's just a waste of fuel
Wiser InTime I have a buddy who has a car Tire on his bike. When I first saw it I had the same response everyone else does. There's no way that thing does good in curves. Ever since then we've ridden back roads and everywhere else. He can ride it no problem on any curves. Even takes it to The Tail of the Dragon. He rides the bike to work 100 miles one way every day. That's 1,000 miles a week, plus what he rides locally every day. If he had a motorcycle Tire, he'd be replacing it once every 4-6 weeks.
chicken strips dont tend to mean what people think they mean, you have have large strips and take a turn harder then someone with skinny strips on the same type of bike with same tire size. the ride style will have more to do with your strips. how far you lean off your bike vs how far you lean the bike. different schools of riding that get the same end goal
Very informative, I didn't know about the tyre width correlation to lean angle reasoning. I thought it was solely the size of the contact patch, but as you said, it also has to do with the centreline of the tyre relative to the contact patch.
In an inertia reference frame, it is inertia and therefore not a force. In a non-inertia reference frame, like that of a turning motorcycle, it shows up as a force. However, because it only exists in the non-inertia reference frame, that type of centrifugal force is a fictitious force. There is a type of centrifugal force that exists in inertial reference frames and is therefore as real as any other force: the Newton's Third Law pair force to the centripetal force. But that's not what Ari was referring to.
I knew about affecting performance but never occurred to me that could affect the braking and the suspensions. Glad to know that because I was going to install a 240 on my Raider 1900 next year. It’s a good thing that I’m not an unconditional modifier. Modify at all cost, no way. Thanks.
This is really pretty wrong. First of centrifugal force (not centrifical) does not exist. If it did exist and were in equilibrium with the friction force from your tires you would not turn. It is the imbalance of forces that causes the bike to turn as opposed to staying at rest (meaning constant velocity). Second a wider tire does not always mean more grip. Friction (traction) is a function of normal force (the force ground exerts on the bike to balance out gravity and down force so you don't just fall straight through it) and is not reliant upon the area of your contact patch. However on sports bikes that use extremely grippy tires the friction forces from cornering and acceleration can exceed the strength of the rubber for skinnier tires, causing it to sheer off the tire body. By using a wider tire this stress is distributed over a larger area so that the tire stays intact and can use it's maximum possible grip. As such if you just take some random bike that is already optimized and just put a wider version of its current tire you don't gain any grip, just worse handling.
+River Carson Centrifugal force is inertia. No need to split hairs about it because you know what he means. Wider tires maintain a consistent patch while providing enhanced resistance to shearing, so therefore, a wider tire will - in most cases - provide better traction. Bikes are rarely "optimized" around a particular tire. It's usually what the OEM was able to score the best deal on, and that will often be a popular size. Your logic of "OEM knows best" is faulty...because the OEM is faced with delivering a product that is profitable at a specific price point using manufacturing facilities with minimal retooling.
nice video, good advice. I have a 1994 CBR1000F and have just come back from a 1,777kms ride on a 180 rear tire. Was a great ride (camera running the whole way...)
informative video. I would say my super tenere has narrow tires to keep as much contact patch on the ground while traversing off road or gravely terrain. speeds on those surfaces are much less that on paved surfaces so there is no need to lean as much, keeping the tire upright. as the video explains it would also allow for better turn in on the street.
Excellent first-level introduction to this topic - thanks! Please set up a more technical, 'Moto-Nerd' channel, to go into much more detail on these topics. We badly need a channel, that's aimed at dispelling the common mis-information about motorcycle chassis-dynamics - that would be a true public service!
Could you guys maybe do a buying guide for second hand bikes? Like a walk around check list of things to look for and what to listen for when the bike is running. Love the channel, keep up the sick work guys :D
My GSXR 1000 uses a 190/50/17. But I run 200/60/17 Pirelli SC V3 or Dunlop Q4 190/55/17. I actually just ordered a set of each in those exact sizes! I would always recommend a 190/55 over a 190/50 rear tire! The bike just leans in so much easier.

Check out @motojitsu channel i bet on my life he'll be more than the help you need
This was my exact experience at the track lately. I ride a Yamaha R3, and the tire vendor didn't have my size, but suggested I try a larger: 110 to 120, and 140 to 165 (the smallest they had), and I lost about 50% of cornering performance, and the bike felt like it leaned another 10 degrees without trying - I had to lean even more to corner and the exhaust started dragging

Tire width has more to do with tire curvature profile, target temperature, heat dissipation, while maintaining proper rotating mass as it relates to gyroscopic precession... than overall width, contact patch, and ultimately looks.

Just like why race boats have knife-edge bows compared to a cruise ship. Cutting vs plowing.
giff74 Also larger diameter wheels and tires offer better off-road handling and overall performance when the pavement ends.

Those with say a 10" front wheel are much less stable than those with a 12" front wheel.

Another great video!
Thats what many people like to do here in Indonesia, they use 190/55 on a Ninja 250 or Yamaha R25 (in Indonesia is 250cc version, not like Ninja 300 or Yamaha R3). They just swap the tire rims with the wider one, like 5.5" wide and use that big wide tires over a quarter litre engine. Mostly, people use 160/60 on the rear wheels on a stock rims, 4" wide. I guess they just want to look great with the wider tires, instead of having a good performance on their bikes.
I completely agree with what you explained in the video, and I learn something new!
WicakSOUNDno Thanks for sharing bro, i didn't know they could fit such a huge tyre on 250s! I plan to replace a 150 size over the stock 140, do u think it's suitable? Or would it compromise the handling too much? So many people tell me it would improve corner grip, i just need to be sure.
gronkgrunk But of course they changed the arms also, usually they install arms from bigger bikes,
Its suitable just fine I believe, I ride Yamaha R25 on the front 120/60 and 160/60 on the rear.
I guess for the corner grip is depending on what kind of tires that you are using, either soft, medium, or hard compound, and how confident when you are taking a corner with your bike and stock tires.
WicakSOUNDno some people sacrifice performance for looks. everyone has a different taste. but personally i would max out on performance :D
I put a 150 on my CBR250's 140 rear. Not for looks or performance or whatever but because the Michelin Road Pilots only come in 150 and larger and those are the only tyres I would ever want on my commuting bike. Bike felt like it wanted to drop into a lean more quickly due to steeper profile but no clearance issues or any issues for that matter.
As for performance... a much wider tyre on 250/300 will only hinder performance. Bike doesn't have enough power or weight to need the extra grip and will only have to accelerate a heavier weight.
iSYKE Same here man I put on some Pilot Road 4s today and they only have them in a 150 and a 120 where as the PR3s came in a 150 110, great tire
Another interesting thing about tires and lean angles is that when you lean, because the tire is curved you essentially decrease its radius and essentially lower the gear ratio causing the bike to increase engine RPM relative to speed.
Wow great segment on tires! I've been and still am a tire technician for just over twenty years and Im impressed with how accurately you explain the many different types and uses of tires. Especially proper inflation. Love watching your videos good job guys👌👊
This is actually the sort of discussion I was hoping MC garage would go into when I found the series, really looking forwards to continuing.
ADV bikes have skinnier tires to focus their weight onto a smaller area on the ground and increase traction.
that's not how it works. If you take friction alone, the force stays the same regardless of contact patch. T=μN
Nice R1, B&W with red details looks awesome
Great video.. there's a guy at Cycle Gear actually tried to talk me into putting a 190 tire on my rim that usually has a 180 on my FZ1... he said it didn't matter people do it all the time.. thanks to videos like this one I went back with the proper tire size.. just goes to show just because bikers work at Cycle Gear doesn't mean they actually know their stuff...
The FZ07 has a 180 rear. I didn't even realize it for like two weeks of owning the bike. I figured it had a 160 since it's a 75hp bike. But nope, 180.
Well it will keep up with one in the corners no problem. Infact I've seen Mt 07's beat R6's round corners, whilst obviously the R6 left them in the dust on the straights
@Malcolm Brody fcuk off
@@bellator11 Mt's have a lovely chassis, couple that with the light weight = a lil fun machine
That's another reason why the MT07 are awesome motorcycles 🏍
Professional, no bullshit approach is so refreshing
Thanks for making his video for us! I´ve learn a lot! Always watching you guys!
Greetigs from Argentina!
Talk about tyres such as this vid don't get nearly as much attention as they deserve. After all, it's arguably the most important safety aspect of any bike. Good and correct tyres = less risk. This vid was a great education. Thankyou! 👍
I'm not a motorcyclist but I'm sure you guys will always appreciate some feedback. I only clicked on the video cause it was an interesting question. Super professional video! Love how you didn't get arrogant or throwing around gangster signs and didn't swear - I feel like a lot of MC channels have fallen into that hole. Keep up the good work!
Ari, your MC Garage videos are fantastic!
Short and concise and very educational. My go to place for bike maintenance info.
Speaking of wide tires on cruisers, I was really amazed at how well the XDiavel handled its giant booty. Ducati really did their homework on that one.
You answered a question that a new Rider such as myself was dying to know the answer to! Don't hesitate in getting more sciency! Thanks man.
My guess... Because wide tires are like sleds and narrow tires are like ice skates- control. Plus the center of gravity issue form the vid. Off road, lean angle looks like trouble.
I'd also think their lightness would factor in as they travel up and down more and over a greater distance.
That last question is exactly what I was looking for the answer. Ehehe.
I do own a Honda NC 750x, and comparing rim sizes with the Africa Twin, realized that the second one has more narrow tires but bigger wheels. Interesting to know what that sizes improves offroad handling.
Please do continue with your awesome videos.
Cheers from the Azores Islands - Portugal.
I ride big adv bikes (honda varadero 1000) and we use narrow tires because is more heasy to handle this kind of heavy bikes, also, we don't need to lean as much as a sport bike to make fast corners (not as fast as a sport, but still fast), and also with a wide bag setup, we can also lean a lot or we will be scraping the crap out of the bags...
thank you. ive watched at least 10 videos so far and none of them were as informative as this one. you win a subscription lol
as always ... so darn helpful.. thanks MC garrage
Good explanation on the matter and you're absolutely spot on. I was doing a track day with a local club in NORCAL and had a 2017 R1 running 190's. I couldn't believe how much I had to lean her over to get through the same turn compared with 2000 Ducati 996 SPS running 180's. Later that afternoon we installed 170's and the bike felt more nimble even less lean angle and still knee down on the Mazda turn at BW watching a Super Duke with two up videoing me as it was passing with less lean almost straight up on the turn!!! Always got spanked around the corners by the 250 cc class who never used brakes before entering and through the corners. Your realize quick how vastly different performance is with different bikes, different tires, and different setups and how it is different at different points on the track.
I love your tips,you very professional and you have helped me very much during the years
Can't agree more with this. The factors you mentioned are all spot on. Also, manufacturers (at least here in Indonesia)actually suggest "tolerance level" for various rim sizes if owners are not satisfied with the stock tires (though to be frank, the suggested sizes are just one size up or down as you have mentioned ).
As a side note, I was often asked the difference between U-shape profile tires and V-shaped profile tires. All I can say is that these refer to the tires' tread shape when they are installed on the rims and that U shape tires give better stability on tight turns while V-shape tires are good for long corners with the same tire size. It would be a most welcome if you guys have better explanation for this and share it here.
I really love watching MC Garage videos. It's very informative and inspiring. I hope you guys keep on making them.
Great video, very interesting and answered a lot of questions I had about tire size, thanks!
I'm a long term rider and never heard this answer before. I learned something new and I love learning about riding and I love the MC commute vlogs too. Keep up this format along with your current style. I'm a serious driver and decent backyard mechanic, but not too familiar with the motorcycle physics,dynamics or other parts. I just ride because I love to and use my lil 600 Bandit as a commuter here in NorCal.
Thanks guys, love your work
As far I remember from high school grip doesn't depend on the actual size of the footprint but from the weight force and the friction coefficient
Interesting! I presume the narrower tyres on ADV bikes are to cut through soft mud to get traction on more stable ground beneath as opposed to a wide tyre just floating on the mud?
id say having nobbies would adchieve this, a wider tire should also be best at gathering as much grip as pissible.. i'd say it's a cost-thing
Maybe the leaning and weight; ADV's already weigh alot so shedding weight from the tire might help. And as he said in the video, narrower tires don't have to lean as much
I know from my experience with tractors. We often fit narrower tires for some types of muddy/ hilly conditions. It is true that wider tires cant get grip on loose or slippy surfaces. while a narrower tire with the weight of the vehicle acting on it bites in and grips much better.
That said. In really deep mud. a narrow tire can have you stuck up to your axles so in that case you might opt for a wider tire to help you float better.
I had an YAMAHA RD LC 125 EIDS(ENERGY INDUCTION SYSTEM) PRE YPVS in the 80`s and used a MICRON POWER EXHAUST/UPGRADED THE AIR FILTER TO A POD METAL MESH! K``n `N POD FILTER(this sucked in water when the weather in blighty/GB was wet:( I had BOYSEN RACING REEDS and NGK RACING PLUGS, plus I upped the main jet and raised the throttle lift circlip to corrisponde/COPE with the extra fuel and I kept the tyres sizes standard at first but played around with the compound by buying metzelers BUT upped the front to a size bigger and had a standard size rear.
The outcome was a extra 10 hp and a 5 mpg more thirsty beast to begin with.
But it was genuinely faster and harder to turn into bends at first but it did hold the line better at top speed of 80 mph and also stopped the bike from wandering on the straights:)
My conclusion is fatter tyres give the bike more stability in a straight line but make the bike harder to turn:)
PPS I had a FORD XR2i (FORD FIESTA) and put widder pepperpot wheels on it and when it snowed they were SHIT*:(
I put narrow tyres on it and they were as you would have guessed brilliant.
This must be the best MC channel on RUclips! I have been in "fatter" tire discusions 100s of times..
Narrower tires are better off road, more weight per square inch. For street, narrower tires are usually cheaper. Another good video.
i would have thought it helps them cut through loose surfaces to penetrate to a firmer gripper surface, which coincides with your comment
if narrower tires are better off road, then why air down? Bigger footprint = more traction.
I've always fancied myself to be more educated about tires than most, but I actually learned something from this video. Great job as always.
The chicken strips on that r1 were so juicy, the colonel called and said he wanted his recipe back...
Best RUclips channel for bikes knowledge.
I prefer narrow tires for the increase in how easy it is to flick.
One of my favorite channels, basics well explained. I was surprised, when I had the chance to test ride a Yamaha FZ-07 today. It has a 180 rear tire but handles pretty good though.
And here i am with my Honda cbr 125 with a 100/80-17 backtire
Even my 50cc scooter has a 140 rear tyre
This video helped me to understand wide over narrow tires. Thank you. I am using only a scooter. Honda Click/Vario 150cc..
Go use tractor tires
What about car tires on the back of gold wings?
Absolutely love MC Garage videos, you guys rock, especially Ari.
ADV bikes aren't designed for high grip situations, they need lower mass tires to facilitate navigating (pushing) through different terrain.
I went from 190/55 to 200/55 and love it and will never go back to 190/55 , I 'm riding s1000xr
Better stability but way worse for handling. The bike won't want to change direction as fast.
My changing directions has not been noticeably change but cornering in & out is way better also tire wear has improved :)
I am going to have to agree. I only weigh 155lb and the advantages far outweigh the disadvantages, such as braking. I also think to turn well, it is your technique and timing more than your tire size; however, different strokes for different folks. If you have a 250 or 300, it is obnoxious to go up to a 190. To swap the rim means you are taking something from somewhere else. I am not saying you will like or dislike it, I am saying it has to come from somewhere else.
Darrell im riding LC135 Yamaha using 160/60
thanks for stepping up the technical details and accuracy in this tire overview. much, much better than the radial vs axial break technical overview. keep up the good work.
nice job ari
Great visual representation of how larger tires can affect lean angles!
I switched the stock 140/70 tires on my ninja 300 to 150/60 Bridgestone battlax tires and would never go back. Yes a little bit of me wanted a fatter back tire but the really reason I wanted to switch was for stability.
The 300 was way to flickable! The damn thing was hard to hold in a line going around corners, it didn't have a very planted feeling at all. The wider tire makes a noticeable difference without wasting money on silly upgrades such as suspension and steering dampeners.
I decided to go for 60 mm aspect ratio simply because it made the least amount of difference on the overall circumference, thus no need for a speedohealer. Not to mention that the stock tires were awful, more than glad I decided to switch!
airton soares
stock tyre size was bad or the IRCs?
do you face any difference in performance?
Aditya Mohan
Both the stock IRC tire and stock dimensions Kawasaki chose to be honest. I noticed that the IRCs lacked grip. Specifically, the rear wheel tended to slip during hard breaking and quick launches. In terms of performance, the bike rides better overall, mainly during curves like explained before. The battlax tires provide a lot more grip, in fact I am not afraid to lean in as far as possible with them. I'm not sure if the new tires weigh more. If they do, the power loss isn't very noticeable. In my opinion, the bike was far too wobbly while leaning in with the stock tires.
So what do u reckon? A lower profile tyre does the job better for Ninja300?
airton soares nop.
150/60 may weigh a slight less than 140/70
I was thinking of doing the same switch on my R3. The stock tires are horrific, and every time I do research anyone who did the switch said they immediately felt a difference in overall feel of the bike. They also felt more confident as well. And MC Garage here also said the Bridgestone S21(battlax) are the way to go for a nice performance boost.
Out here in new york tho, and it's stored away for the winter. I gotta wait until mid march to do anything T_T
definitely enjoyed it. i would also be happy to see a more detailed breakdown of this topic, too
But wait, isn't grip (friction) dependent on the force pushing the two materials together, in this case the tire and the road, and not their surface area? As in, shouldn't two tires with the same weight but different contact patches, still offer the same grip? Obviously big tires are fitted on bigger, heavier bikes, but does the increased contact patch really offer more grip by itself?
@Austin Yount, it's rather more complicated than your formula makes out. That's the formula they give in early physics classes, but the reality is a bit more complicated than that.
The area of the contact patch definitely does make a difference, otherwise people wouldn't underinflate their tires in order to gain traction. It's still the same material, but it's warmer, wider and stickier than a more inflated tire would be.
As for centrifugal force, nope, sorry, he didn't say that. He said centripetal force, which I took note of as it's so rare for these videos to bother getting that right.
Chris L I know it's much more complicated than that. After all, the formula for force of friction is well known to be only an approximation as with pretty much all classical/Newtonian physics. If we knew everything, we wouldn't be relying on approximations but we don't know everything and our approximations are extremely accurate. So accurate in fact that the engineers who designed the cars and the tires used these same approximations in their design process. I think that contact patch is important as well but it doesn't really seem like anyone knows exactly why. You do bring up an interesting point in regards to underinflation. My hypothesis would be that an underinflated tire flexes and bends more causing it to heat up and get stickier as you said but what does stickier mean? Stickier actually means that we've changed the coefficient of friction. the same piece of rubber will have a higher coefficient of friction when it's hot. I would also think that a wider tire or underinflated tire would be better at coping with road irregularities like pebbles for instance because it is more likely to have another part of the contact patch pressing on stable ground. remember these are all just ideas. No one has been able to answer this question that I'm aware of.
As for him using the word "centrifugal" vs "centripetal" force, I've listened to him say it multiple times and my ear hears "centrifugal force" every time. But it really doesn't matter in this case because he goes on to talk about "the force pushing to the outside of the turn" which we both know is practically the dictionary definition of the mythical "centrifugal force". So either he stated the correct force while completely misunderstanding the physics involved or he stated the mythical force while still completely misunderstanding the physics involved. The two words are not interchangeable. Whichever way you cut it, he's still wrong.
*in regard to ... (no regard(s)). Regards(s) indicate good wishes or respect as opposed to the singular 'in reference to.'*as regarding ...*as it regards ...Better yet ... 'concerning'
Grip is not equivalent to friction. Friction works as you described, but grip has more components than just friction. Tires are made of a softish compound because that allows it to "grip" onto a rugged surface, such as asphalt, and the bigger the contact patch, the bigger the surface that can interlock.
Why do you think centrifugal force is "mythical" or "imaginary"? It's just a force that exists in the rotating non-inertial reference frame. As far as the moving motorcycle is concerned it is a very real force.
Great info. I was doing a lot of googling about installing a fat rear tire on my Honda Shadow, but after watching this video I think I'll stick to my stock 170/80-15.
Smart. The bike was engineered for the stock size.
I have a 2009 honda shadow. The speedometer was way off. About 10mph. I put the next size up tire on the back years ago and it’s way closer to actually speed along with zero real world handling draw backs I can tell.
more like this.
Gladly i watched this bfor throwing up some oversized rubbers on my r3. Thanks men. More informative videos to come and more power to this chanel.
this channel is my motorcycle information channel..
great content.. keep up the good work 😀👍
I really enjoyed this. I have been thinking about changing the width on my street triple from a taller 180 to a lower 190 for the looks, but didn't wanted to compromise acceleration. I'll probably stick to 180 though.
Didn't know the difference and characteristics of the lean angles between them. Now it makes total sense why I feel that I lean much more on my diavel with a 240 than the triple with a 180.
Thank you very much and keep up the good work!
I love this channel
Ari Henning, please also review why all bikes are handled by default from the left side and not on the right. I just thought about it. Anything from the right feels uncomfortable. Thanks and your reviews rock!!
When you're cornering, accelerating, braking,.... tires are doing work. But rubber's work isn't 100% efficient and that's what's causing wear and heating (and tire drag or rolling resistance).
The wear is caused by rubber going out of the tire due to friction. The more the tire is gripping the road texture (due to pressure), the more you have grip (you can even go above 1.0 coefficient of friction with good tires and good conditions). But if it stressed (pressured) too much, the rubber in contact with the road will just tear appart before it was able to do all its work and you're losing grip.
In conclusion more surface (wider tire) DOES NOT equals more grip. There's an equilibrium point between "rubber deformation gripping road texture =>|
Fun fact :
In the efficiency races (1 galon gas races, etc...) they don't bother that much about grip but energy waste is a big deal! In these kind of races they prefer super hard compound and super thin tires. It is more aerodynamic, it causes less rolling resistance or tire drag and it lasts longer!
In regards of energy efficiency, wide soft tires are a nightmare.
There is never "always good" or "always bad" features, wether a thing is good or bad always depends on what you're looking for.
And then theres me. I will switch the 140 to a 160 on an MT03 because i just like riding wider tires. Idc about all that other stuff haha
While you are right About most points, i fail to understand why a wider tyre should make your contact patch bigger ceteris paribus.
Outstanding explanation of tire width vs. lean angle!
how important to warmed up your engine, before hitting the road?
Same as a car, 10-15 seconds
Just let it idle until you have good throttle response
That's a great video Ari .. I've gone through the gambit of trying to run wider tires on my bike for the last year and came back to the exact mentality, stock was best for a reason - I corner and accelerate much better on skinnier treads .. Wish you'd have made this last spring hahaha ..
when changing tyre size will effects the speed...?
Generally, the wider the tire, the more rolling resistance it will have. This can have a very significant effect on something like a bicycle, but on a motorcycle, I doubt you would even notice it.
Something very important to consider when choosing what tire to put on a bike 300ccm or less is the friction. Wider tire causes more friction, it makes very small difference when accelerating, but it can change the top speed by a lot, so if you are doing a lot of motorway riding, make sure the wider tire doesn't put you below your cruising speed.
wider = better grip/better stabil, harder for turn/manuver, slower/more power loss
narrower = less grip/less stabil, easier for turn/manuver, faster/less power loss
thicker : less grip/less downforce, faster
thiner : more grip/more downforce, slower
why slower?
@@lanchanoinguyen2914 yeah. Actually faster in cornering. That's why 300cc and 600cc will beat a 1000cc in twisties. Smaller the tire, the better the handling.
Example: a Toyota Supra can beat a Dodge Charger in twisties because of less weight.
Really good video. Thanks for doing these videos guys. Much valued.
a larger contact patch doesnt mean more grip
Jorge Chávez, yeah it seems to be a common misconception.
Yep, but they do deform and wear less though
Yeah rubber is weird lol
Man. I wouldn't want to engineer tires. That's not even as complicated as tread patterns.
And then there's compounds, operating windows of temperature etc etc
My 2015 BMW 1200GS has the 170 on the rear and its probably the best road handling bike I have ever ridden and Ive ridden a lot including sports bikes super nakeds etc. The GS's handling is sublime
i love that white R1
Thanks, that centerline point/ lean angle is interesting.
8 people don't agree with physics.
Back when you can see dislikes
Wdym we can still see em@@thenovalabs
Width relationship between front and rear is another hugh consideration towards expected behavior. Studying the history of the Yamaha SX 650 changing the rear from 18 to 16 as well the Honda 750K verse the 750Four 16 to 18.
"we're gonna get scientific here"
"centrifugal force"
EXACTALY what I was thinking. Centripetal :/
sir your every video contains knowledge which in general people do not talk , thanks for sharing such information with us...
awesome videos by the way.
What does MC garage think about these "dark side" folks out there who put car tires on their bikes?
I you don't have anything nice to say, don't say anything at all? ;)
Wiser InTime Dark side folks haha
Dark Siders is da craziest people!
id prefer to roll with the original tires nomatter what and I don't know about mc garage but I personally think that having a wider tire than what is prescribed for your bike that it's just a waste of fuel
Wiser InTime I have a buddy who has a car Tire on his bike. When I first saw it I had the same response everyone else does. There's no way that thing does good in curves. Ever since then we've ridden back roads and everywhere else. He can ride it no problem on any curves. Even takes it to The Tail of the Dragon.
He rides the bike to work 100 miles one way every day. That's 1,000 miles a week, plus what he rides locally every day. If he had a motorcycle Tire, he'd be replacing it once every 4-6 weeks.
i never fail to learn something new with this guy... thumbs up🖒
Good video . That R1 has some decent chicken strips might need a bigger tyre.............. Cheers
chicken strips dont tend to mean what people think they mean, you have have large strips and take a turn harder then someone with skinny strips on the same type of bike with same tire size. the ride style will have more to do with your strips. how far you lean off your bike vs how far you lean the bike. different schools of riding that get the same end goal
Very informative, I didn't know about the tyre width correlation to lean angle reasoning. I thought it was solely the size of the contact patch, but as you said, it also has to do with the centreline of the tyre relative to the contact patch.
adv bikes have narrow tires so they can sink into the sand and mud and not hit as many rocks etc
Jorge Chávez
I came up with same idea.
Jorge Chávez absolutely not. I really wanna know the answer but that's not it. I ride ADV and you always work to stay on top of mud and sand.
Thank got for this video! I wanted to detailed explanation on rear tire width - This video answers a few specific questions I had!
stick with your stock tire size 🤗✌️
Unless u want more grip, longer life, or stunts or better styling!!
Hmm, seems like it depends what you're into, amir? This channel is brilliant. Brilliant explanations.
Centrifugal force doesn't exist Ari
Kevin Arnold in an accelerated reference frame it does
Dalton Williams which is actually just inertia
In an inertia reference frame, it is inertia and therefore not a force. In a non-inertia reference frame, like that of a turning motorcycle, it shows up as a force. However, because it only exists in the non-inertia reference frame, that type of centrifugal force is a fictitious force. There is a type of centrifugal force that exists in inertial reference frames and is therefore as real as any other force: the Newton's Third Law pair force to the centripetal force. But that's not what Ari was referring to.
Ryan Bax umm, how is the turning motorcycle a non-inertia reference frame?
This is why I'm in engineering and not getting a physics major 😂
Enjoy every video I've seen you make. Thank you.
so its easier to get your knee down on a bike with bigger tyres. interesting
The Vardarioter he didn’t say easier. He said wider bike tires NEED to lean over more to do what thinner tires do normally
I knew about affecting performance but never occurred to me that could affect the braking and the suspensions. Glad to know that because I was going to install a 240 on my Raider 1900 next year. It’s a good thing that I’m not an unconditional modifier. Modify at all cost, no way. Thanks.
This is really pretty wrong. First of centrifugal force (not centrifical) does not exist. If it did exist and were in equilibrium with the friction force from your tires you would not turn. It is the imbalance of forces that causes the bike to turn as opposed to staying at rest (meaning constant velocity). Second a wider tire does not always mean more grip. Friction (traction) is a function of normal force (the force ground exerts on the bike to balance out gravity and down force so you don't just fall straight through it) and is not reliant upon the area of your contact patch. However on sports bikes that use extremely grippy tires the friction forces from cornering and acceleration can exceed the strength of the rubber for skinnier tires, causing it to sheer off the tire body. By using a wider tire this stress is distributed over a larger area so that the tire stays intact and can use it's maximum possible grip. As such if you just take some random bike that is already optimized and just put a wider version of its current tire you don't gain any grip, just worse handling.
+River Carson Centrifugal force is inertia. No need to split hairs about it because you know what he means. Wider tires maintain a consistent patch while providing enhanced resistance to shearing, so therefore, a wider tire will - in most cases - provide better traction. Bikes are rarely "optimized" around a particular tire. It's usually what the OEM was able to score the best deal on, and that will often be a popular size. Your logic of "OEM knows best" is faulty...because the OEM is faced with delivering a product that is profitable at a specific price point using manufacturing facilities with minimal retooling.
You need to go back to school dude.
you guys produce excellent videos that are detailed yet on point, keep up the great work
nice video, good advice. I have a 1994 CBR1000F and have just come back from a 1,777kms ride on a 180 rear tire. Was a great ride (camera running the whole way...)
informative video. I would say my super tenere has narrow tires to keep as much contact patch on the ground while traversing off road or gravely terrain. speeds on those surfaces are much less that on paved surfaces so there is no need to lean as much, keeping the tire upright. as the video explains it would also allow for better turn in on the street.
Hey mcm, we love your videos.. extremely informative.. especially for an amateur like me.. i think bikes use centripetal force when in a lean angle
Excellent first-level introduction to this topic - thanks! Please set up a more technical, 'Moto-Nerd' channel, to go into much more detail on these topics. We badly need a channel, that's aimed at dispelling the common mis-information about motorcycle chassis-dynamics - that would be a true public service!
Man, thanks a lot for your videos. They are informative and straight to the point! Keep it up!
Could you guys maybe do a buying guide for second hand bikes? Like a walk around check list of things to look for and what to listen for when the bike is running. Love the channel, keep up the sick work guys :D
Also quite a broad area. Maybe break it up into price brackets? or Year brackets? Get a couple of episodes out of it :)
My GSXR 1000 uses a 190/50/17. But I run 200/60/17 Pirelli SC V3 or Dunlop Q4 190/55/17. I actually just ordered a set of each in those exact sizes! I would always recommend a 190/55 over a 190/50 rear tire! The bike just leans in so much easier.
Short video, with full of important information. Thank you. 🥰 Love from india
Great video, learnt a lot about the tyres... thank you :)
really loved the video
a big thanks from bottom of my heart
liked , subscribed and also added to notifications
Great topic!! Keep it up with more in depth talks about the "science" of bikes!!
great video and info, but 2:30 you didn't mention the height aspect of the 50vs55
Really good information dude.
Awesome video as always guys!!
Really love your work, keep it up. You guys will get to 4million subscribers in no time ^_^
