I run a mullet set up. Schwalbe on the rear, Magic Mary on the front. Run both at 17psi. I run with tubes. Never had an issue. I have more control with the lower tire pressures and the ride is more enjoyable. I ride a Bulls Copperhead EVO AM 4.
I recently discovered on myself that suspensions don’t work well with very low tyre pressure. 21 psi front and 24 psi rear are a good all round starting point pressure for me.
I have a 2021 trek rail and I usually run between 14-16 lbs. when ever I go to 20 and above I feel like my front tire is washing out. With gear I’m about 180-185.
Great video Steve ! As you say just experiment & have fun in different conditions to see what works for you !! Really enjoyed the short vid. Good work Steve !!!
The issue of tire pressures, are the trends, with today's tires and suspensions it is rare to lose traction and more in the easy climb of the video, 10psi? oh really? What about rolling resistance? Do you want to see how your battery burns? How long will your wheel rims last? better to have a good margin of safety and improve the technique😉
It's proven (apparently) that you get less rolling resistance off road with less tyre pressure. Growing up riding in the 90s the theory was always completely the opposite!
Having come from road riding, it took me some time to get used to low pressures on MTBs. I've now got tubeless with a rear insert so can go pretty low, helpful as I ride all year round & in Lakes & Yorkshire, so it's often wet & slippy on limestone, so low pressure = better traction all around.
I ran 15 psi last week at afan forest,did blade which is super rocky, and slippy,rear tyre was superb at that pressure for that terrain,i think if id have had 25-30 in id have been ,either off,or slipping all over the place
I have 67 Kilos, my bike 22.5 Kilos and I run (front and rear) at 1,0 bar or 14.5 psi (trail, AM) with Schwalbe Eddy Current. No problems, good grip. Thank U for the video, Steve! Good Job. Greetings from Germany
The problem i see is first getting to the climb ie a lot of road before you get there and putting preasure back into the tyre after you have finished the climb i,ll stick to "normal " tyre pressure and slide around less work.
we ride really rocky trails out here in Arizona, and the smart rider gets Tannus Armour tube type inserts, and enjoys a plush ride, great stability land traction, and never dents their rims or gets a flat. Lots of cactus out here. The inserts let a 225 lb rider run 17psi front, 20 rear, and run through sharp edged rock gardens and it feel like every rock is made of foam. Instead of getting jarred, you just blast over rocks that would destroy rims. These inserts prevent flats, lower rollng resistance, and make everyone that rides your bike think you have the best suspended bike they have ever ridden. There is no way you could run less than 25 psi out here in the rocks without inserts and not kill your rims. Who cares about the tire weight, it just increases stability at speed.
When Steve left Ray's workshop his folding front tyre popped its clogs on the 150mm masonry step. He probably forgot it happened, however for me, the memory of a brand new tyre giving up the ghost so soon raised a question. Reducing tyre pressures was how the Desert Rats got up the sand dunes in North Africa but the old cross ply tyres were heavy and reinforced! Just maybe, a review of a cheaper possibly longer lived wire beaded tyre type would have educated an Old School Cheapskate about folders folding on sharp edges!
0.9bar in the summer 0.8 in the fall. Can't really go lower than that. Or you can but you start to lose capability in handling at that point. 0.9 bar is already low enough that it's definitely not for railing turns.
very interesting, finding that 'sweet perfect tension'. But don't forget that those low pressures are detrimental for the lifespan of those damn €xpnsiv€ tubes!
What tyre pressures do you run? Do you change pressures depending on terrain!? Let us know down below👇
I rarely do anything gnarly so run close to max pressure (48-50 PSI) to get better range.
637psi in the back, 420psi in the front. Gotta have the expanded rubber for that extra rotational traction.
I use tubes and tires 2.4 front and 2.6 rear. Both tires are 22psi on my 78kg weight and the ebike is 24kg. It's probably too much pressure.
15-18 psi front and back depending on terrain and conditions. Running Rimpact tyre inserts too.
I run a mullet set up. Schwalbe on the rear, Magic Mary on the front. Run both at 17psi. I run with tubes.
Never had an issue. I have more control with the lower tire pressures and the ride is more enjoyable. I ride a Bulls Copperhead EVO AM 4.
What pump do you use?
I recently discovered on myself that suspensions don’t work well with very low tyre pressure. 21 psi front and 24 psi rear are a good all round starting point pressure for me.
Run tubeless
My bike is about 30kg
Have 2.6” use 23psi in front 25psi in the back
I have a 2021 trek rail and I usually run between 14-16 lbs. when ever I go to 20 and above I feel like my front tire is washing out. With gear I’m about 180-185.

Thanks, Andrew! We're glad you found this explainer useful! 👍
What would you do with a 75Kg rider on a 22kg bike (Turbo Levo) riding both on the road and in rocky conditions (stones in the wood)?

I like to run about 19psi with a strong tirewall. It seems to work best for me. Super soft tire compound

Good stuff, Neil! We're glad you got into MTB! 😉 Sounds like a good setup! Inserts are brilliant!
That Topeak pump which can do shocks and tyres - with a digital pressure gauge, seems to be ideal thing to carry with you
I put winter nails in the tires.
I re-new them every 100meters cause they damage on rock

I forgot: tubeless !!
You Forgot to say which size ( 2.4,2.6…) and kind of walls : trail , super gravity😉
@@jean-francoislay6471 Bonjour JFL: 2.6, Super Gravity 😂😂😂

It's not too much work if you've got a pump on you!

squishy slo-mo footage. Love it!
Satisfying as heck! 😍

What pressure adjustment would I use for my weight of 114 kilos?
Great video as always Steve thanks 😊, how do you like the scorpion?
I have a Emtb specific scorpion and I love it !!!
Under rated tyre here in Nz 🇳🇿
Running a good brand of insert generally helps with performance at lower pressures I have found 🤙
I knew a guy took an ebike of a 12 year old in a park.....that's pretty low pmsl

Who knows? Under 40psi i don't even ride😂🤟🤟🤟🪓
What's the link to buy that pump?
Loving My Canyon Spectral On !!!
What pump is that please?
0.9bar in the summer 0.8 in the fall. Can't really go lower than that. Or you can but you start to lose capability in handling at that point. 0.9 bar is already low enough that it's definitely not for railing turns.

You're right! It's a trade-off for sure! The more you grip, the faster the tyres will wear
I use 17 psi front, and 18 rear with 2.2” wide 29ers, I weigh 160 lbs
On a 35-65psi tire I run 45-55 at room temp during winter and 35-40 during summer. (temps outside determines the pressure I run my all terrains at)
Steve. Tubes. Just saying.Unsolisosted advice.
