Excellent video!
I'm a heavy rider (125kg) and I was always wondering about tire pressure for my MTB bike, and the info about the TPI is priceless!
Thank you.
nice guide mentioning ur ride style, and weight in relative to your tire pressure of preference. thanks so much!
‘If you need to add more air just pump up your tires.’
Now that is some very crucial technical advice! 🤣
"Most people who died are dead"
love the way you have added all the presentaters in put on tires
Thanks, great to see what pressures you are running on different setups. Qn, would you go higher or lower pressures if you are running a 29er?
Thanks for info, been trying to get ideas for my new tubeless tires. Running 30 f & 32 r. I see no difference going tubeless for my trail riding so far
the old couple in the background of the footage of blake manualing made my day
I agree.
Will be nice to get also a mention of the new 27.5+ and 29+ wird tires, that use less pressure.
My wife runs on an Ibis Mojo 3 (with 27.5+ tires) using ~15-20 psi!
awesome insight! can't fake experience! thank you for helping me out
how to setup your front shock in a hardtail would be an awesome video
I ride an enduro bike, 26" wheels with tubes. My style of riding is enduro (mostly technical downhills but I also climb) and downhill. My weight is 80 kg. What tyre pressure would you suggest me? Thank you very much
For those of you asking what gauge they're using, it's a Topeak Smartgauge D2.
After getting one you'll realize how inaccurate the gauges on most pumps are.
Got kenda k-rad, which is a dirt/street tire. It clearly states on it: 30-80 psi. Running it at 40+ psi, using it for commuting, mostly asphalt, a little bit of dirt sometimes. If lower than recommened 30 psi - it's just not rolling, uneffective. You especially feel it on climbs. So, TMM, take into account recommended pressure range printed on your concreet tire, it's there for a reason.
Tire pressure is all about the volume of your tire and rim combination. On my enduro bike with 2.5in Minion DHF and 38mm internal width rims, I run 20psi front. On my trail bike with 2.3in HRII and 25mm internal width rims, I run 24psi front. I find these pressures work great for me and I rarely have any problems with flats. There are too many variables to claim one solution for each type of riding. I could probably go with a little higher pressure on mine, but I'm not competing in the EWS.
Continental xking folding tl ess 26x2.4 I run at 18 psi front/rear
I race XC and run 20 in the rear and 17 in the front.... tubeless of course... This video was completely alien to me with all these high pressures!
i'm more of trail rider and run 21/24 and was thinking the same thing! A proper tubeless rim (i use stans) provides plenty of tyre support, i weigh about 82kg and have no issues running these pressures
I believe this video is also completely inaccurate what is the ideal pressure for nowadays tubeless rims and tires for CROSS COUNTRY. I would say anything over 20 psi will give you very hard tire that will bounce over roots , rocks and slow you down considerably.
I run in my 29er race bike about 17 PSI in 2.2 tires on 27.5 mid plus bike about 14 psi .
One thing to keep in mind you should not be hitting rim. My suggestion would be (on proper tubeless build) ... start with 20 psi and most likely you will be able to go down. When experimenting with pressure you need quality pressure gauge - say 30 psi pressure gauge (full scale /max pressure this gauge will measure is 30 psi). This will give you accurate measurement. Using pump gauges.. that is another point where they are completely off here, they simply do not show correct reading... they may be consistent in showing incorrect reading... so if you "map" you pressure on Pump to correct pressure you can do it that way and know how much you putting in.. but much simpler is to buy $12 low psi gauge
Should be proportional to your weight. A 300lb dude is going to compress the same spec tire more than a 100lb person. The relative “hardness” of the tire would be much higher for the 100lb person. This is the same concept as suspension and fork setup. Different weight, different psi.
I weigh 200 lbs. I still race XC and I still run 17/22 Goahead. :D
I have 29x2.4 Continental xKings 38psi front and rear and this is perfect for everything. No punctures very fast over any surface with great grip and i even use them with tubes :) epic tires
Test out putting helium in the tires to save weight.
We're afraid it doesn't work :( The helium leaks out!
Fill the frame instead?
You could use nitrogen but I don't think you'd feel any difference, they do it in motor racing because it doesn't expand as much at high temperatures. If you've got more more than sense though 👍
@@maxbailey2688 you already get like 90% nitrogen with regular pump air. Word in the street is that just a $ maker.
@@bewimotos yeah, you might as well clean your ears to save weight but if it's what you want to do
Trek Fuel Ex trail bike with tubeless: 22 back and 19 or 20 front. If very rocky go up 10%. Great grip and no rim damage!
Hi cool video just wanted to ask a question with regards to my tyre pressure. And my body waight my Bodley waight is 19 stone and I have a giant advance 1 xtc 29er I'm runing noby nice evo tyres with a. High pressure of 50-60 in both front and back. I don't have a car and so cycle every. Wear from on the rd to dirt I was lookin for advice on what pressure I should use any hellp s and tips would be great best wishes ken
I had to rewind to make sure I heard correctly when he said tubes were fine... seems like everyone's pushing tubeless these days. Good to see someone with a different opinion.
when I got my bike the guy in the shop said 40psi but felt I was pinging off of everything, after a few rides I found playing around in the mid 20's with about 10% more in the rear than front felt best for me.........now I just go by feel, if it gets too squishy I'll give it some air
I'd love some more info on Fat, Plus and Cyclocross pressures. Plus how to determine the best pressure for each rider.
Great video folks...Thank You for the info.
We ride primarily cross-country with a lot of abrasive sharp rock gardens and thick growth of acacia but totally dry trails. i often find sidewall of the rear tire torn. now i have switched to Schwalbe Hans dampf for rear and Maxxis crossmark / ikon on the front. the wheels are tubeless and i weigh 75 kg. Currently i ride with 28-30 psi. What do you think is a good range?
I'm 65.8 kg on an AM hardtail. I just switched to tubeless, Maxxis Minion DHF and DHR II. I run 20 PSI front and 22 rear and have never had a pinch flat or burped the tires. I don't really notice the tires squirming around, but should I try different pressures?
Run quite high pressure for moving between trails on asphalt
#askgmbn what Tyre pressure would you recommend for a light weight rider at 57kg with maxxis tomahawk in the back and schwalbe Hans dampf up front both in there toughest and heaviest edition, I am not running tubeless and I mostly do fun and aggressive trail riding and sometimes bring the bike to more Enduro styled trails.
Just got a 2017 Spec Enduro Elite 29er. Would you recommend going to a wider tire? OR changing to go lighter? Tubeless yes but I see many are ditching the stock slaughter/butcher tires in favor of lighter as the E29 is already on the heavier side. I am a fairly inexperienced rider and plan to utilize the several training vids you guys have to get better but so far I have a Syntace Megaforce 2 stem is 30mm and 40mm coming as my bike came with a 60mm stock and this should improve that 'sweeping' motion. But I will say I almost got the 6fattie Stumpy as I liked the 3" tires. So will a 2.6" be a nice compromise? I want to get a little bit of that big tire feeling back. I'm just a casual rider, not a lap speed guy at least yet. I do have only the 29er Roval Traverse rims thus far.
what are the recommendations for 27.5+? I am 185lb with my pack and am running 14-16 rear and 13-15 front depending on conditions.
I’m 106kg and I’m riding a Stumpjumper Comp Carbon 29 with 2.6” tires. I was using the tires that came with the bike for the last 1,300km which had the weaker “Grid” casing. I had to run 26psi in the front and 32 in the rear otherwise the tires would fold under hard cornering or flat landings. I just upgraded to a Butcher front and Eliminator rear with the tougher Black Diamond casing and I’m hoping I can run lower pressures. Do you think a tougher casing will allow me to drop my pressures by much, if so, how much? I have them set at 22.5 front and 27.5 rear as a starting point but I’m yet to test them (maybe tomorrow after work). Any advice would be appreciated.
can you please do a pro bike check on scotty's downhill bike? the rear suspension looks so complex...
Yanay H it's the same as brendan faircloughs and they did a bike check for it.
it actually won't be the same as brendan faircloughs, he has a custom linkage for his gambler where as i imagine scotty will have the standard linkage that the gambler comes with so they will actually be slightly different
It's actually a single pivot! :P Scott has the other linkage for their preferred progression.
SG - MTB is correct on this one, there is no pivot along the chainstay so it would behave like a single pivot. The linkage are all there for packaging keeping everything low for a longer stroke and keeping forces pointed towards the stronger BB junction instead of bulking up the downtube.
Yanay H they did one on Marc's downhill bike which is the same bike
Can someone suggest me should i need change my saddle to higher or lower? which one is good for long track?
I weigh 180 lbs. (close to 82kg) and I just started experimenting with PSI. I am not going tubeless. I put some brand new tubes in my tire that allows up to 60 psi, and pumped the rear tire up to 40 psi. The ride was the smoothest and the fastest I've ever had, but after about 2 weeks, I hit something hard that made my bike jump. I was about 5 blocks from home and my bike seemed fine. I woke up the next day, and my rear tube was completely flat. It would not hold air at all. After removing the tube, I noticed the punctures were on the inside, near the rims. I checked the tires for any thorns/glass and did not find any. My rim tape also seems fine, it's not worn out or crooked as far as I can tell.
I put another new tube in and started pumping it up to 40 psi again. It made a pop like sound at about 35 psi that startled me, but I was able to keep pumping and after a couple hours it did not lose any air. I rode home from work later that night, and the ride home seemed flawless. After waking up the next day and getting ready to go to work, my tire was completely flat again. This time, it only lasted one day. I took the tube out, and the puncture was also on the inside, but in a completely different spot, straight across from the valve, when the first puncture was a few inches away from the valve. I checked the tape around the rim, and I still can't find any damage or spokes poking through.
Could too much PSI for my weight be causing my tubes to puncture quicker? I've been riding home for 4 years + and never had this problem. I think my pressure has been way too low in the past, as everything such as wind and uphill terrain has been a pain for me.
I tried patching the tubes, but the holes must be too large so I replaced the tube yet again. I pumped the tire up to 30psi right now and I'm going to leave it over night. I hope the tire isn't flat when I wake up and if it isn't, I hope it doesn't go flat the next time I ride it.
Did that fix the problem?
Hi, I'm having trouble choosing the right psi. I weigh 55 kgs, I am relatively short my height is 5feet 2. I am also using tubes on my Kenda tires. Hope you guys can help me. Cheers!
Please can you talk about set pressure by the body weight!!!
What if I use a dirt jumper for street what type pressure do I use please answer ASAP thanks
Any chance of Testing Parlee cycles and also Head in the next year?
I ride MTBs mainly on road and easy trails, waterways. Run approx 50 psi and I really move and roll fast. Watch soft chunky on moist tarmac when cornering esp if you have been throwing bike around for while on dry
Neil i ride on trail king 2.2 wired tire, its 1kg hevy and its a bit draggy on uphills(like my brake is half way on) especialy when you ride in rewersed direction on rear, witch modell is that on your bike?
I’m replacing my muddy fox 24 inch at Christmas for an Islabikes creig (I’m ten) on that Front: Maxxis ardent 26” at 23 psi back: Maxxis ikon 26” at 26 psi. I’m starting to race Xc in Scotland where I live
Cool! That is a serious bike. My daughter was ten last week and I got her a rigid Ridgeback 24 with upgraded tyres just to get her onto some light trails. Hope you enjoy your Creig.
Good details and advice. :)
Are you running tubeless to get the low pressure ?if you use tubes what should the air pressure be?
i weight 46 kgs and ride a hardtail,what pressure do u recomend?
Great video guys good info
My tyre pressure ranges from around 25 psi when I'm riding on a beach to 80 psi when riding urban. I always run tubes so I can swap tyres quickly and easily before a ride.
So I'm a beginner, and I'm trying to jump a long/tall step made out of concrete on a flat surface. Not too sure what they are called. but I can clear off the front tire, but I can't seem to clear off the back tire. My tire popped from an aggressive hit to the back tire. I recently learned to clear of both tires, but this time I didn't time it right. And I ended up getting a flat. Do I need to have the a medium pressure on the tires rather than full when jumping?
Hey guys, i love your videos, i would like to ask you for help on tires, i find myself constantly tearing my tires off ripping them from the sides, 5 tires in 2 months riding on my XC bike on really rocky terrain, i'm actually riding down hills with no path or trails whatsoever just making it as i go, what can i do to avoid this, it's getting pretty expensive and i can't seem to find a solution, are there tires with side protectors or something like that? greetings from chile!
There are tonnes of options for tires with sidewall protection! They aren't really XC tires though (they tend to be lighter weight and lack the protection) so look into more of a trail bike tire. they'll be heavier but more durable for your style of riding!
Love my Magic Mary front and Nobby Nic back combo for the winter months. I ride the woods around Sheffield. Any advice for a summer combo?
We're big fans of the Trail Kings from Continental for summer conditions! They roll very fast for a 2.4 wide tire!
I have a 30 to 55 psi tires and put them at 50 on both works fine for a trimmed ebike that goes 50 km/h and it easely gets 40-48.5 km/h on high power.
how about tyre pressure for enduro-ing? more leaning to XC or DH?
those topeak pressure gauges are the mutts nuts aren't they , got one for xmas and love it , so easy to use and bang on accurate too :)
what tyre pressure do you suggest for me : novice 94kgs 6'3"
great vid!
Always run rear super hard for less rolling resistance and no rimpacts. But you get less traction and connecting feel on the trail. Trying Vitoria Tire Inserts at the moment - so far so good. Always run front soft but, trust me, don’t ‘burp‘ your front tire. The ground hits you in the face before you hear the “PPFFFISHH!!!”
Great video 👍👍👍
what if I ride an aggressive plus hardtail and I keep getting snakebites between the rim and the beed what could I do?
tires are maxxis rekon+
Thanks very helpfull.
I like that you have multiple people telling what they do & go for, it makes it seem more truthful almost 😅
Guys I am struggling to find the right pressure. I am riding a Cannondale Bad habit 27.5 plus. I have a tubed set up using either a Rocket Ron or a Nobby nick depending on conditions. I am 6'3" and weigh in at 265lbs all kitted up. What is a good starting point for pressure?
Cool video,now tyre pressure guages vary so much,how accurate are shock pump guages and floor pump guages,also those digital guages aren't cheap,maybe you could cover this too.
I am currently running 23psi on my enduro bike front and back,it feels quite hard,but this is going by my pump guage,who knows how far out that is.
thats quite a good point, even with pressure guages there is tolerances etc, my two track pumps seem to under read but thats fine as I set up the tyres to the minimum by the track pump, before tyre squirm started to annoy. which for myself for both my weight and style is 30psi ish!
U should get ten different types of tyres , ride the same track over and over with the different tyres and see the major differences. And keep up the good work and it would be really cool if you could if meet up Seth from Seths Bikes Hacks
Hi GMBN, Yesterday i was pumping my bikes wheels and i didn't check the psi and today bad thing happened when i did go for the turn i lost control and crashed i was surprised what happened.
Hey very good info for folk there but I do feel that you may want to include fat mountain bikes too because many around are having a full squish and a fattie both and it's def good info to add. Keep up the great vids!
Thank you!!!
lol when you go to a local bike shop in most areas, there is a massive range of like four tires ; probably three of them being specialized or Bontrager. They are one of the things where it's much better to use a site like Jenson IMO.
i ride best with 21 psi front and rear. its also quite comfortable and grips very good uphill when its raining
Front Tire is a rocket ron 2.25 and rear is a Continental mountain king 2.2. no snakebite or some kind of flat tire in seven years. terrain is forrest and some rocky paths.
what pressure gauge was used in the video? Looking to buy one
I ride a hard tail jump bike, and often ride trails and downhill, but also use it to ride to the trails. What tyres should i buy?
Sounds like your riding a lot of distance just maybe get a Kevlar tyres for the endurance and there fine for dirt jumper at like 2.2 or 2.35
Silly question, the 2.5 Maxxis tires I'm running say min pressure 30psi. Is that more of a recommendation to prevent burping?
A video all about tire pressure and no mention of how overall tire volume affects things?
before I ask what tyre pressure but forgot to tell you the bike. i'm riding a specialised camber 29er 2.3" tyres, I usually set them both around 40psi
i have an old gt bike with 26 inch tires. Ive recently seen at the local dollar store some 26inch tires for $4.99 are these tires worth my ten bucks and time ?or should i just pass?im super broke right now thats tge reason i ask
I would like to see 27.5 covered for Clydesdale rider's like myself, I chose this plus size due to I'm older now and feel it will help with my lacking ability to ride like I once did in the mid 90's and will absorb some of the hits, but I'm almost 260 lbs now so tire pressure is going to be critical . nobby Nic's F&B I'm guessing 18 or 19 F & 22 - 23 rear tire pressure 27.5 x3.00
How much do you weigh Neil? I'm running trail kings 2.4 black chilli apex front and back, tubeless on my Capra CF pro weighing 70KG fully kitted at 20/25 psi front-rear. Couple higher in rocky terrain.
Can running too much psi in tires cause spokes to come loose? I’m 250 been running 35 rear 31 front
Very helpful. Thanks Neil!
If you have tube less tyres on your bike already how do you change the tyres for new ones
Can you add the pressure in bar on you graphics next time please? It's a good video but I kept stopping it to do the conversion to understand it. Cheers
21st century, catch up ;)
@@userwatttt the comment was 3 years ago.... dont think hes gonna look at this lmao
Who uses bar anymore or stone lol
Can you do a segment on rolling down steep rocks that are at least 2ft to 10ft. Trying to avoid Otb. I lean back and have front tire rebound set pretty quick. Just want to see you guys do it and talk about pace and body position.
Here you go! ruclips.net/video/ZmYzLDkeRh8/видео.html
Global Mountain Bike Network thanks I've watched that one (Great video by the way ), the rocks that are giving me the problems are the ones that are vert or near vert and 2-3' where your tire doesn't have much transition if any. if I have speed I will jump them but the ones where there isn't room to get the bike lifted, the only option is to basically drop the tire straight down and hope you make it.
#askGMBN what about hardtails? What type tyre and at what pressures would you recommend.
When you say "a heavier rider" how much weight are you talking about? I'm 96kg, strong and an aggressive rider, I usually run 28 in the front and 30 in the back but that's what the guy at the shop recommended for me. Not tubeless yet and running [F] Schwalbe Nobby Nic 27.5x2.25" Performance Wire [R] Schwalbe Nobby Nic 27.5x2.25" Performance Wire also been thinking of going up to a 2.5 maybe 2.6, any advice?
Would love to see an equivalent of this for cyclocross!
What brand of pressure guage was shown in the video ?
Where can I get one from ?
It's a Topeak pressure gauge 👍
My tires say 40-65 but at around 15 i feel like it’s already getting close to popping..am i missing something? I use my m12 milwaukee inflator and set it to 105 kpa, or 15 psi.
Still a confusing subject as I get told by quite experienced riders to run lower pressures in my tubeless so it's better grip for climbing . On the Stans Sealant site using their formula for my riding weight 70kg , it is 21psi front 24 psi back ? Here in Townsville most of the track have rocks sometimes very dusty on the way up.
Good! Good information on tires. I need what is the name of the compressor and digital. And where can I buy both? thank. ;)
Untold mythic Me too I still do not know what the names of this...
Topeak SmartGauge D2
#askgmbn i ride down hill with many tabletops and jump. should I go tubeless or stay with a tube
Suggested tyre and pressure for 6 foot 3 rider, 130kg, 27.5 hardtail riding on light tracks, gravel, tarmac? Any ideas guys
What do you ride on now? I am pretty much the same maybe around 120kg and i ride on about 30psi front and back
Hi , may i know why is recommended to have lower psi at the front and higher psi at the back on the bike? Thanks
because you generally have more weight on the back tire
I run 35-40 because I need to ride about 7 miles to trails and 7 back and I don't want any rolling resistance
Bring a mini pump
@@connorhalpin2305
Good idea.
What circumference of 26×2.125
I’ve been pumping my tyres up to the max it states on the sidewall ! 😂
Same here lol
Oh no
@@exist2758 What do you mean oh no - just ask Sam Pilgrim ;) He might have some good air pressure tips for suspension too :D
Haha, it must be quite bumpy ride if you hit any potholes or bumps.
I have never measured the pressure, i just pump enough air so the tire doesn't flatten too much under my weight (100kg)
My sidewall says 70 PSI, but my rims say 40 is the max on tubeless tire with the width I have. I'm running right about 38
Rock hard & lets roll baby!
I`m pretty sure you mean fewer threads per inch for a tougher tyre? Fast flexible folding tyres tend to be high tpi which is great for speed and comfort but not so much for durability. Lower TPI tyres have fewer threads as the threads are thicker. Just to avoid confusion.
maxxis exo casing is pretty lite for the protection it offers
Neil!! no mention of Fatbike tyres And pressures!!!
Jon Cobb 10-15 psi
Ben - I run 5 on the back and 6 on the front...
I'd be curious on Plus tire pressures as well. I have 27.5x3" tires and run 16f/18r for mixed riding, but 10f/12r right now for winter snow riding. I'll probly be up around 22f/24r this summer, but it's all trial and error
Jon Cobb run 400 psi back and front....the tires should explode
Jon Cobb Right? No word on air volume and how it affects the pressure range...
will you make more videos with blake ?
so nice...
Could you please tell me where I can find the digital pressure gauge mentioned in the video?
