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.
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.
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.
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 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.
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
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.
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
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.
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 👍
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
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!!!”
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’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.
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!
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
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
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.
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.
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
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.
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
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.
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'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
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'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?
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!
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?
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?
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.
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?
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.
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?
For some reason my air pressure in both tubes they seem to go down after a week. They have no punctures or valve leaks. However, I did get new tyres which have a soft side wall but I'm no sure.
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!
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?
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.
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.
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!
In the worlds most vague answer ever it depends ! but my set up is to have a very fast roliing tire on the back and something grippy up front for cornering grip if I can get away with it, and if its really muddy/steep then something grippy on both the front and back it really depends on the enduro event. I'm pretty light at 57kg ride reasonable smoothly and don't puncture a lot and I really value the extra grip that comes with running low pressure but I don't know if I could recommend many people running what I do.
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.
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
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.
I dislike mine and wish I had never bought it, because when connecting as it's pushed on you let a bit of air out before it seals and if it was at the right pressure if before I checked it's now its under so you have to re pump . Now I find it's easer to just put the Floor pump on in the first place . So really there just a waste of money
A bit extreme to say it's a waste of money. Just pump up to more than you want, and then release the pressure with the yellow button. I'm using one now, and surprised how inaccurate my track-pump guage is.
its' only a waste of money if not used I suppose and I don't use it. If you use the same floor pump all the time and pump to what you want it will ok even if its out a bit, and its quicker and not so much fiddling about
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.
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)
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
Why do usually recommendations say +2 in the back. For example 28 rear 26 front. What is the benefit for this configuration?. I'm a XC racer about 182 pounds and usually use 28 in both tires but XC races in Chile sometimes have a lot of rocks and loose terrain and I feel I would feel better with 24 but then when I go back to flat or not technical terrain I would have slow rolling. Just some advice. Thanks.
The rear tyre is more prone to pinch punctures and doesn't need the same levels of grip as the front, therefore you an get away with and often need slightly higher pressure.
I recently switched to a plus bike. I weigh about 165-170 lbs, and have been running around 17 front, and 20 rear. I think I can go a bit lower though, I'm gonna try 15, 18 for the next ride.
From those I have talked to and from my experience on 27.5 plus 15 to 18 seems about average though it's definitely something you'll want to experiment with. On my 29 plus bike I have been running 10 to 12 psi, pretty amazing there's such a difference between the two wheel sizes.
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.
I usually just use my mountain bike to ride to school (mostly on a footpath, about 3/4 of the ride to school I go onto the bike track which is paved) and I was wondering if like 43 psi is fine?
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.
love the way you have added all the presentaters in put on tires
‘If you need to add more air just pump up your tires.’
Now that is some very crucial technical advice! 🤣

Did that fix the problem?
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?
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

Test out putting helium in the tires to save weight.

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
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...
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.
Tire pressure changes the spring rate on front forks and rear shock
I like that you have multiple people telling what they do & go for, it makes it seem more truthful almost 😅
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

Good idea.
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?
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!
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 :)
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?
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?
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.
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?
Great video folks...Thank You for the info.
What brand of pressure guage was shown in the video ?
Where can I get one from ?
It's a Topeak pressure gauge 👍
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.
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?
Continental xking folding tl ess 26x2.4 I run at 18 psi front/rear
Can someone suggest me should i need change my saddle to higher or lower? which one is good for long track?
For some reason my air pressure in both tubes they seem to go down after a week. They have no punctures or valve leaks. However, I did get new tyres which have a soft side wall but I'm no sure.
Same thing happens to me too. But I check/adjust my pressure before every ride
Yeah. Like I know that temperature affects pressure but it's about a 10psi drop and the temp here hasn't lowered by much.
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!
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?
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.
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 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.
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!
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’m wanting to become a machanic and I hope this helps I want to be a michanic for my brother for his racing
Any chance of Testing Parlee cycles and also Head in the next year?
What if I use a dirt jumper for street what type pressure do I use please answer ASAP thanks
and for enduro, which pressure and tires should I hace??
have* no hace
In the worlds most vague answer ever it depends ! but my set up is to have a very fast roliing tire on the back and something grippy up front for cornering grip if I can get away with it, and if its really muddy/steep then something grippy on both the front and back it really depends on the enduro event. I'm pretty light at 57kg ride reasonable smoothly and don't puncture a lot and I really value the extra grip that comes with running low pressure but I don't know if I could recommend many people running what I do.
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.
What about for commuting?? I have the maxxis hookworm 2.5x26 for commuting.
If your mostly on the road then run a high pressure, therefore meaning less rolling resistance.
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 like to run very hard tyre pressures, 45 to 60 psi but each to there own
Heads Tails // so I'm not the only one (i prefer to ride high pressure because you feel more the bike and the terrain)
Me too. I ride around 40 psi with Maxxis tires and 45 psi with studded Gazza Extremes.
For me it's more like 55/60 psi (on enduro bike)
I like the jumpiness of higher pressures when going fast down rocky trails
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.
Wish you had placed a link to that digital tire pressure reader.
Just pause the video...... Topeak Smartgauge D2
www.topeak.com/global/en/products/pumps/351-smartgauge_d2
I dislike mine and wish I had never bought it, because when connecting as it's pushed on you let a bit of air out before it seals and if it was at the right pressure if before I checked it's now its under so you have to re pump . Now I find it's easer to just put the Floor pump on in the first place . So really there just a waste of money
A bit extreme to say it's a waste of money. Just pump up to more than you want, and then release the pressure with the yellow button. I'm using one now, and surprised how inaccurate my track-pump guage is.
its' only a waste of money if not used I suppose and I don't use it. If you use the same floor pump all the time and pump to what you want it will ok even if its out a bit, and its quicker and not so much fiddling about
what pressure gauge was used in the video? Looking to buy one
how about tyre pressure for enduro-ing? more leaning to XC or DH?
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.
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
Rock hard & lets roll baby!
If you have tube less tyres on your bike already how do you change the tyres for new ones
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
Can running too much psi in tires cause spokes to come loose? I’m 250 been running 35 rear 31 front
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
maxxis exo casing is pretty lite for the protection it offers
Why do usually recommendations say +2 in the back. For example 28 rear 26 front. What is the benefit for this configuration?. I'm a XC racer about 182 pounds and usually use 28 in both tires but XC races in Chile sometimes have a lot of rocks and loose terrain and I feel I would feel better with 24 but then when I go back to flat or not technical terrain I would have slow rolling. Just some advice. Thanks.
The rear tyre is more prone to pinch punctures and doesn't need the same levels of grip as the front, therefore you an get away with and often need slightly higher pressure.
Great video guys good info
What about pressure recomend for 27.5 plus? Tks
I recently switched to a plus bike. I weigh about 165-170 lbs, and have been running around 17 front, and 20 rear. I think I can go a bit lower though, I'm gonna try 15, 18 for the next ride.
From those I have talked to and from my experience on 27.5 plus 15 to 18 seems about average though it's definitely something you'll want to experiment with. On my 29 plus bike I have been running 10 to 12 psi, pretty amazing there's such a difference between the two wheel sizes.
29+ seems like it would be a lot of fun. Just monster truck over everything
Haha yeah it's awesome, probably not great for really short riders but at 5'11" I love it.
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'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!
In my full suspension bike I always was using 32-33 psi in rear wheel 30 psi in front wheel ,
I am not downhill rider by the way and my weigh is 92kg
What's perfect for 70kg weigh
why is your first name eyetalian and your last name german?
What about Dell's mountain Bike tires that you can get a Walmart are they good
Rim width also makes a difference.
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.
What about for snowy conditions?
I ride 45 psi with studded Gazza Extremes.
I usually just use my mountain bike to ride to school (mostly on a footpath, about 3/4 of the ride to school I go onto the bike track which is paved) and I was wondering if like 43 psi is fine?
Yeah that's more than fine.
Hamish Anderson cool thanks for the feedback mate.
i weight 46 kgs and ride a hardtail,what pressure do u recomend?
My bike has V-Brakes and the brake pads are scraping the wheel when I'm not braking. How do I adjust/fix this?
CyrBronc • Yes both of them, mainly on the front tyre
CyrBronc • Not really, no. I'm quite new to mountain biking. What do I need to be adjusting?
MrFaceTech // try playing with the "bolt" on your handlebar side and if that doesn't works try to adjust the cable on the "wheel side"
