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.

[@pippipster6767]

‘If you need to add more air just pump up your tires.’ Now that is some very crucial technical advice! 🤣

[@oynamaqe892]

"Most people who died are dead"

[@joshuahunt1210]

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!

[@symanoy]

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

[@happy2818df]

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

[@jaykan1002]

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.

[@Muzsolutions]

I weigh 200 lbs. I still race XC and I still run 17/22 Goahead. :D

[@owenpreece4508]

love the way you have added all the presentaters in put on tires

[@X_Squared_X]

For those of you asking what gauge they're using, it's a Topeak Smartgauge D2.

[@takeit1229]

After getting one you'll realize how inaccurate the gauges on most pumps are.

[@marcusgarner1]

[@nickturnbull5454]

I agree.

[@RepresentWV]

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.

[@leonid998]

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.

[@esteevius]

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.

[@MarinePredators84]

Did that fix the problem?

[@CoryFoster]

A video all about tire pressure and no mention of how overall tire volume affects things?

[@bikoastal9203]

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.

[@Yanai_H]

can you please do a pro bike check on scotty's downhill bike? the rear suspension looks so complex...

[@mickletterbox]

Yanay H it's the same as brendan faircloughs and they did a bike check for it.

[@JMBMTB]

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

[@SGMTB]

It's actually a single pivot! :P Scott has the other linkage for their preferred progression.

[@jonowee]

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.

[@plokooon4246]

Yanay H they did one on Marc's downhill bike which is the same bike

[@dkerkmez]

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?

[@davehoover8853]

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!

[@garygilbert1127]

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

[@appealinbanana]

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!!!”

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

[@andrew.triggs]

I'd love some more info on Fat, Plus and Cyclocross pressures. Plus how to determine the best pressure for each rider.

[@irvsstella]

Tyres are designed to run at certain pressures, lower pressure =fatter foot print, higher pressure= higher roll speed. Ride out to the trail on high pressures, drop from 55psi to 35 psi, ride trails, pump up, ride home.

[@brentmiller6922]

Tire pressure changes the spring rate on front forks and rear shock

[@skullfucker3381]

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.

[@Infinity-ok6fe]

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

[@MrDblStop]

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.

[@rbid]

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!

[@calvinjonesyoutube]

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.

[@beckygrumbridge4553]

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

[@gregkosinski2303]

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.

[@philt6725]

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.

I like to run very hard tyre pressures, 45 to 60 psi but each to there own

[@themountainsbros381]

Me too. I ride around 40 psi with Maxxis tires and 45 psi with studded Gazza Extremes.

[@themountainsbros381]

For me it's more like 55/60 psi (on enduro bike)

[@zachocking3906]

I like the jumpiness of higher pressures when going fast down rocky trails

[@WildOutdoorLiving]

Definitely to each their own, just a word of warning though, many mountain bike tires aren't rated for more than 50 psi, exceeding that could lead to blowing the tire off the rim.

[@colmherbie8261]

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

Everyone forgets about narrow rims needing more pressure to not flex horribly and loosing grip when cornering on hard surfaces....

[@withstyle7816]

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.

[@RichJ-nr1ho]

I can't believe how high their psi is. I normally do 17-20 psi front and 24-26 psi rear. If you run too much psi in either tire the ride will feel horribly stiff on singletrack, doesn't even matter what kind of suspension the bike has. A tire with high psi literally ruins the function of suspension on the bike. Not to mention the front tire can bounce right off the trail if it hits an obstacle wrong.

[@Scott-mu4xw]

Rim width also makes a difference.

[@QoraxAudio]

I've always been running my tires at 2.5bar/35psi, but recently, I discovered that my touring bike has tires specified at 3.5bar minimum!

Great video folks...Thank You for the info.

[@wholesalemonkeyfarm]

Why do they recommend higher pressures for rocky terrain on mtn bikes? That’s the opposite of powered vehicle off road where the rule of thumb is to air out to maximize traction.

[@randomvideosn0where]

I go crazy high sometimes like 70-75 psi but usually run around 40. Depends on what you're doing and I'm also a pretty big guy. The other day I was down around 20 because I was riding on snow and it worked way better than the high pressures.

[@CarljDiangco]

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.

[@Gojira_Wins]

The critical flaw in this video is not addressing the body weight VS tire pressure difference. We watch these videos of dudes who mountain bike with tire pressures in the low to high 20s yet they have the body mass of an average high school boy. There are various body weights out there and even for myself, I weigh 280lbs at the moment. If I ran anything under 50psi, my tire and rim would absolutely break doing through even mild trails. Just making a video saying "I run 25psi, you should too" is WAY too unprofessional for a varied audience that may not understand the difference between being 150lbs on a bike and 200lbs on a bike. Yet they make a MASSIVE difference. This needs to be addressed.

[@bullwhipjohnson8247]

Folders for sure no matter what type of riding. Tubeless or not I always carry a spare inner tube.

[@rollinrat4850]

I run 18-28 psi depending on trails , ghetto tubeless. I go as low as possible without banging my rims too much. I ride in lots of rocks. Sometimes theres more rocks than dirt!! I want traction and comfort and reliability above anything else.

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.

[@omproductions188]

I’m wanting to become a machanic and I hope this helps I want to be a michanic for my brother for his racing

[@SupppaFly]

stan's has a simple formula. for me seem to be workin good "To determine a starting tire pressure when running NoTubes tires with our ZTR rim use this simple formula. Rider Weight in pounds divided by 7 = x x - 1 = Front tire pressure in PSI x + 2 = Rear tire pressure in PSI Example: 185lb rider 185/7 = 26.4 Front tire pressure: 26 - 1 = 25 PSI Rear tire pressure: 26 + 2 = 28 PSI "

[@timmlpsk]

SupppaFly Haha so for my weight it would be 19psi front and 21 psi rear :D I don't think thats accurate

[@skyking166]

why do you think it's not accurate? At any given pressure, a heavier mass will compress the tires more. If I remember correctly, when weighted, tires should be compressed about 15% from its neutral shape, also known as tire drop. If you're much lighter, you run a lower PSI, but the % of tire compression you get when riding will still be the same. As far as worrying about having too little psi and thus striking your rims, well, force is not generated by the ground, it's by the mass of the bike + you. Force = Mass X Acceleration, acceleration generally equal to gravity, unless you apply downward motion. Less mass = less force. In short, I would imagine the equation still holds true in terms of % tire compression even if you're super light, but would add a few psi more just for safety due to bead coming off/collapsing (cornering force which is mainly from speed and g force), for any additional acceleration on top of gravity 9.8m/s^2 you might exert on the bike (you're free falling after a jump, and for whatever reason decides to slam your bike down), and for internal deformation (sprinting? where the low pressure + casing alone might not be enough to hold the shape of the tire for side to side sprinting motion). If you're wondering, I weight 134lb, and yes, I do run ~20psi. Dry I usually run ~20 front, 22 rear, and wet/snow/slippery I run ~18 rear 15 front. This is before I have seen this equation. According to the equation, I should run ~21 rear, 18 front. So I'm pretty much right on the money. Also worth noting is your bike geometry and weight distribution. If your bike is setup to have most of the weight back, you might want to run a few extra psi in the rear than suggested. Example, XC bike will favor a more forward, front heavy position, so that means you should probably run a little more PSI in the front, meanwhile a DH bike might favor the back more. Again, all about that % of tire compression. Also keep in mind that higher pressure have a placebo effect that you're going faster because the frequency of bumps on the ground is higher since you feel more bumps stiffer tires).

Are you running tubeless to get the low pressure ?if you use tubes what should the air pressure be?

[@weserve042203]

Silly question, the 2.5 Maxxis tires I'm running say min pressure 30psi. Is that more of a recommendation to prevent burping?

[@MrGnarman]

Higher TPI usually denotes a lighter tire though...

[@SANATRATH_GWR]

My fatbike is 26*4. Max psi quoted as 30 psi. My question is "What is the max psi to be maintained on my fatbike if I go for a century ride on smooth tarmac highway ?" I have seen few videos which states that max psi will make the bike bumpy and max speed cannot be attained.

[@michaeltowler2632]

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.

[@skullfucker3381]

This is important even for casual driver especially if u have an ebike let's tell it like this if you own a car it requires a bit of knowledge to maintain it the same applies for a bike, I accidentally had low psi on my ebike and had just felt with my hands but then I got an indicator and makes the world difference, if you comute daily check it at least once a week as u loose pressure with every ride.

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!

You cannot do spesific pressures with pumps sold in stores. Scale on pumps are very bad and pointer is very thick so impossible to inflate exactly like 29psi.

[@richardmiddleton7770]

25-30 PSI on 2.4's! What are you like 100KG?! I'm running 11 front 14 rear on 2.2's! If it was rocky I'd probably go 15 front 20 rear.

[@markprice1614]

Being a "heavyweight" 220 kilos (and a less than great rider) I always run a bit more pressure than I should. Always worried about a blowout.

[@antred11]

220 kg?? What kind of giant are you?? 😮

[@pierrebroccoli.9396]

Many variables to take into account. Tire diameter, width, casing, tubeless or tubes, rider weight, riding style, inner rim width and discipline. For example, enduro 29er bike with me at 85kg kitted on trails, 2.4 rear and 2.6 front on i30 rims tubeless, I will run 22psi front and 26psi rear. If the conditions are a bit rough and rocky then I might add a couple psi in the rear to take the hits but I will leave the front as is as it is a large volume tyre and I try to ride smooth and light on the bike - preferring front end grip. XC 29er hardtail with 2.35 tyres on a i21 rim - then I will run 26psi front and 30 to 32 psi rear tubeless. Any lower and the rims don't like it but I do suffer traction issues with that setup. i25 rims with lower pressures would be a better choice. Tried running lower but the front tyres would burp if too low and the rear rim would need truing after a ride.

I run 3 on both

Great video guys good info

[@wakeawaken430]

I thought that high tpi means a more flexible tire(which means higher psi)

[@kolbemorgan2999]

u spelled tyre wrong

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.

[@rogercmerriman]

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!

[@urielruiz3937]

Like!! We need more downhill!! My dream is all the people practice montain bike!.

[@Bryan-df7kc]

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.

[@shullinger6]

If I'm going to be riding my mountain bike as it were a street bicycle, then would a different tire pressure be more logical? Such as ... ?

[@edwardpage9996]

If you have tube less tyres on your bike already how do you change the tyres for new ones

[@rowdybroomstick1216]

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

[@Big-T-]

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?

[@acidfriend47]

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?
