MrTdw1954 I did this once to my rears when rotating to prolong my right camber wear; the only difference is at highway speeds above 70mph tends to vibrate the car. Those thread groves facing opposite direction actually grabs air. Fascinating
As a general rule of thumb, directional tread pattens tend to perform better in wet straight line braking and aquaplaning. However, they also tend to be noisier and they're no good as a spare tyre because they can only be mounted on one side of the car! Directional tyres are being phased out in the EU because they cannot meet new stricter noise regulations. Ultimately though every tyre is different. You need to read reviews and performance tests for the models of tyres you are looking at.
Thanks for the video. I just had set of tires with asymmetrical design installed today. After looking at them i see one tire has been installed backwards. With side's reversed. Back to the tire shop tomorrow !
This was a great explanation of the differences between these tires. Awesome job. I just wish you had told us the model of each of those tires. I really liked the pattern on the assymetrical one!
The advantage of asymmetrical tires is lost when all that is required is that the tire be turned on the rim to spread the rate of wear over a tire surface and also the ability to rotate tires around the vehicle - however, they do look pretty on the vehicle and also helps tire turnover for the manufacturers - very bad for the environment getting rid of the carcasses. Excellent video and accurate explanation.
Thank you for this video, Going to rotate the tires on the car and at the same time change the oil. It helped me to understand what I will be doing at the time I get to this job! Perfect Thanks
Make no mistake those two tires are very different and perform at their peak at entirely different temperatures. The tire on the right would get you through a few inches of snow quite well when the tire on the left would have you in the ditch.
I drove my asymmetrical summer tires with just a light snow dusting one day before my snow tires came and no they cannot drive through anything I was side ways for 6 miles because it had a light dusting while I was in a restaurant. Both will put you in a ditch
Regarding the environment, a tire is a tire. As for the tire pattern, certain patterns are great for driving in snow. Plain circumferential patterns are lousy in the snow.
This is a great video because I was looking at the Nokian WR G4 SUV, which is both directional AND asymmetrical, so this helped me think about that clearly. It seems possible that a set of four symmetrical, directional tires could could be composed of four identical tires, so long as they are also symmetrical in their centers where you mount them, so that each tire can be mounted with either side facing out. It is also possible that a set of four asymmetrical non-directional tires (like the ones you show here) could be composed of four identical tires. But a set of four tires that are both directional AND asymmetrical must consist of two tires designed to be on the right side and two mirror images of those tires on the left side, and that you could never rotate the tires from left to right because such a rotation would result in the directional pattern pointing the wrong way. Could you please comment on this? Thanks! Here is a link to the Nokian WR G4 SUV at Discount Tire: www.discounttire.com/buy-tires/nokian-tire-wr-g4-suv/p/39870
Here is a link to Nokian's own illustration of how the directional grooves on its asymmetrical tire work. Clearly if this tire is approaching you, it must be on the driver's side of the car (in the USA), and the tires on the passenger side must be mirror images, and so the left and right-side tires are not interchangeable: www.nokiantires.com/innovation/innovations/blade-grooves-nokian-wr-g4/
It depends on the tyre quality and pattern design and the type of your car as well. I've noticed in my experience that directional tyres in general are better and more stable when you drive on a smooth road with no cracks, holes, anomalies or upsides downs which roads like this in my country are only found on the motorway. In the city most of the roads are simply awful they are full of anomalies and cracks, holes and unpredictable surfaces so asymmetrical tyres are able to handle better.
Thanks for the video Jay/auto123. I just received some new tires today, previously I was only aware of symmetric or directional tires. The ones I ordered are asymmetric so I was confused looking at them. I think the confusing thing is that the tread still seems directional on an asymmetrical tire. What I mean is it looks like the same tire flipped rather than mirrored, the outer tread grooves angle forward on one side but back on the other.
@boy638 The tire compound makes an even bigger difference and varies from tire maker to tire maker. It's not possible to say that all directional tires are superior to assymetrical tires.
So weird I somehow still don't what the the difference between the 2 is? Or what reason to choose between the 2, I don't think he explained this, the title threw me off
So the difference is, they look different?? Neither are better in the wet? Both have bits to make sharper steering happen? I think pros and cons would be a nice thing to tell everyone, it might help with the selection... for example... asymmetrical tyres can be rotated on a car, which should increase their wear-life.
ryanmail2004 Sure, but if an Asymmetric tyre has outer large blocks and a strip in the middle, and a Symmetrical one does too, but the tread is all facing one direction.... they are both still equally good? I bought Kumho KU31's and stuck with symmetric tyres for the lack of seeing any benefits of asymmetric ones. Having all the rubber dedicated to going in one direction MUST be advantageous for performance, and perhaps a disadvantage for wear.
The title of the video's a bit confusing, you can of course have asymmetric directional tyres so this would've probably been better split into two separate videos. The right hand tyre should be mounted with one side always on the outside; the left hand must be mounted with the sipes facing in the direction of travel (with diagonal vanes forming a 'forward arrow' from the inside to the outside to push the water out). In the video example, the right-hand asymmetric tyre would likely be better in extreme wet / snow conditions due to its larger surface area, smaller centre rib area (unlike the directional tyre, which is not vented along its rib circumference - aquaplane much?) and the siping pattern giving it more surface area and more vanes for water. However this will probably give it inferior dry grip. The composition of the tyre material will affect cold weather performance as much as the pattern; the higher the silica content the faster they'll wear but the more grip they retain in cold temperatures (less than 7 degrees celcius), a huge advantage for winter driving - better lateral grip, superior stopping distances. Anyone in northern US states or Scandinavia is well aware of this...!
Interesting. I say "advantageous" because I imagine that having ALL of the tread grooves flowing backward would disperse more water than a tyre that has only half of the grooves facing the correct direction. As for dry performance, my blocks have a chamfered edge too, which suggested to me that the load being put down going forward would flex the blocks less than if the blocks stood upright with square edges all around. I'm only arriving at these assumptions by looking at the various designs. The Kumho's were very reasonably priced compared to all other tyres on the market when I was buying, and so far i'm quite impressed so at the end of the day if there is a small percentage difference here and there i'm probably not going to notice it either. Less is more, in the dry you are correct. In the dry I don't have issues with car control though, so instead of running slicks or semi-slicks i'm after the best wet-performing tyre I can find. Street tyre performance is moot for me... if I track my car I don't use my street tyres. I would be interested in a breakdown of both types of tyre though... is one generally better in the wet, dry, longer wear, etc.
The outside of the asymmetrical is on the left not the right in the video. Those larger blocks serve the same function as the center rib of the directional tire.
Can you explain which type of tyre michelin primacy 3 is? If i mount tyre on wheel correctly (outside/inside), can I make a mistake when mounting a tire on a car?
Well explained my prefrance would be asymmetrical because you can cross rotate your tyres for longer life how ever the rotational tyre can also be rotated but only on the same side it is on this also can prolong the life of the tyres condition
What is the best tire rotation for asymmetrical tires. I have three set of michelin brand X-Tour A/S, X-Tour and defender and they have similar tread patterns. Is it cross pattern (LF to RR, RR to RF, RF to LR, LR to LF) or Front and back ( LF to LR, LR to LF, RF to RR, RR to RF). Thank you so much.
Auto 123 ~ What are the differences with regards to rotation options comparing a directional tire and an asymmetrical tire? Also between the two performance tires in the video (I think it was a Yokohama on the viewer's left, and a Continental on the viewer's right) which one would be better to use during dirt rally cross stages, or would you suggest a different tire entirely?
I believe that the advantage of an asymmetrical tire is that you can rotate tires to either side (passenger or driver) of the vehicle without having to remove the tires from the wheels and remount them. This is because one side of the tire always faces outward so when you flip it to the other side of the car it is correctly oriented already.
Are asymmetrical tires directional? It doesnt have a "Rotation" stamp but if you put it on the other side of the car the inner tread pattern will be reversed.....does that matter?
Asymmetrical tires allow you to rotate side to side, front to back or back to front, or even cross rotate in x pattern. Directional tires you can only rotate front to back or back to front.
Directional tires - area and pattern has little influence on adhesion between the Tyre and road surface (UxW) is the formula - circumference channels are all that is needed to shed water. The chevron pattern on a Directional Tyre makes little sense at all - simple circumference channels would do the job getting shut of water. The more rubber area the better for wear resistance - more tread pattern more heat not more grip. Heat reduces the Tyre life - proof just study slicks in motor racing.
I would say NOT directional, because being staggered the left rear tire can ONLY be mounted on the left rear and the right on the right, you won’t be able to relocate from front to back
the shop i went to got my directional tires, front two winter tires on backwards meaning opposite direction i don't notice handling issue ..what can happen short-long term ? HELP?!
JUST PURHASED 2 NEW FRON TIRES Geotrac patagonia AT ROWL 245/65R17 AND I DONT SEE ANY MARKINGS FOR DIRECTIONAL OR NON DIRECTIONAL SOHOW DO I TELL WHAT THEY REALLY ARE?
+Rondo Schiavoni yeah it doesn't matter the direction or the spot on the car unless the car has different sized rear tires than the front which is called staggered
your speedo might be off by 1 or 2 mph thats it. i have made this same change and has no real issues with the speedo. now when you change the width of the tire is where scrub radius changes.
there isnt a difference, asymmetrical last longer as you can swap the tyres from left to right and back n forth, directional you can only go left side front to back n right side front to back. You can buy the same tyre in either variety
“The benefits of the idea of making a car wheel that has three tiers” * The car does not overturn if the car is driving fast or if the car is driving slowly. * Continuing the car's movement without stopping in the event that one of the tires explode. * The driver will not stop to change the wheel or change the tire. Destiny is in the hands of God, but prevention increases safety. Note : God willing, I will make an iron wheel, its size, for example: 6cm * 8cm * 6cm, and the sizes of the iron wheel vary. Ebrahim.
The differences are in the expensive tires and basically modern asymmetric tires offer the same lateral stability as directional tires with a better ride quality. But for the average consumer you just have to take the advice of the tire retailer as to which will be better for you. If your tire retailer doesn't as what kind of driving you do with your car then go to a new retailer because your current one doesn't know what they are doing.
Just say the true straight. On your left you have an all season tire with high technology performance DSW (dry, wet & snow). And a peace of s#$% on your right. Of course for a half price
looks like someone threatened to kills his family if he didn't make this video
If you run directional tires backwards it can cause a rift in the space-time continuum.
So I could turn any car into a time machine...
427SuperSnake1 Nice!!
MrTdw1954 and with 1.21 Gigawatts, you give power to the Flux Capacitor making time travel possible.

They did this and now im stuck here

The ride attribute details would have been nice and the wet weather performance on the different tread would be an interesting addition.
@Azureecosse The downside of high performance tires is that they are extremely noisy. They are less comfort oriented.

Christopher Woods Not exactly. There are directional tires that run in the opposing direction of the V shape made by the tread.
What is the color of line/dots mean ?
That extreme contact dws06 on the right is a sick ass tire itll blow the one on the left away hardcore
I'm pretty certain that the one on the left was a continental new summer and the one on the right was the off-season
The outside of the asymmetrical is on the left not the right in the video. Those larger blocks serve the same function as the center rib of the directional tire.
any advice as to which has the best performance?

Is the new Continental Pure Contact tire Asymmetrical, meaning it has to mounted to roll in a certain direction ?
Are asymmetrical tires directional? It doesnt have a "Rotation" stamp but if you put it on the other side of the car the inner tread pattern will be reversed.....does that matter?
The pattern itself is symmetrical latitudinally (X, , I and - patterns, instead of V patterns) so it doesn't matter.
what about when it comes to rotations?
