This video contains paid product placement for Pirelli. Getting your mountain bike tire pressure right for you, your riding and the tyre itself is vital. It will significantly improve your own confidence and ensure you're getting the best performance from your bike.
Tyres are one of the most important elements when it comes to the performance of your mountain bike - after all, they’re the only thing connecting you and your bike to the ground.
There is a vast amount of variation when it comes to tyres. Some, such as their diameter, are obvious, others, such as their carcass construction less so.
Sound scary? Well don't worry I’m going to talk through a few rules of thumb to help you get your tyre pressures just right.
As ever, drop a comment below with what pressures you like to run and how you came to that decision!

'riding with a more point and shoot style' is a nice way of saying 'riding like a bag of anvils'

@sixtysecondsofstephens2386 3 года назад

Great advice, I was running my 2.6 width tyres with to much air.

I'm between 88-90 kg these are my preferred pressures front/rear, both setup tubeless. 140/130 mm trail bike w/ 2.4" tires on a 29mm rim: 21/23 psi 100mm XC hardtail w/ 2.2" tires on a 21 mm rim: 24/27 psi

@steveco1800 3 года назад

I went from 20mm inner rim width to 25mm for my 2.3 inch tires and it vastly improved the handling and reduced squirming. Before I had to run 25psi to keep the handling precise but it was a bit too hard for my weight, now I can run lower pressure with better handling.

@bikeradar 3 года назад

Nice upgrade! Thanks for sharing 👍

@Raumance 3 года назад

Run at around 2.3 bar rear 2.1 front. It's not really enough pressure to rail turns the tires will fold in tight berms but that kind of turning doesn't really happen outside the bike park. Might drop to around 1.8-2 bar rear depending on track, which would obviously mean the bump compliance matters more than turning. Years ago use to run around 1.5 bar, lot of snake bites. Only time I go above 2.3 bar is for specific riding in a bike park where folding is a real problem.

@CarkeekW 3 года назад

I use a ratio of 6 front to 7 rear , i have cushcore so it depends where i ride, 18 21 for rooty tracks , 24 28 for flowy stuff with bigger jumps . Currently im running 2.6 on 35mm internal. Obviously i run in-between those pressures to suit all round tracks. 6 7 only works for same size tyres front and rear , if i run a 2.8 r and 2.6 front ill likely run the same pressure.

@superawesomefuntimego 3 года назад

Generally 2.4-2.5" tires I start at 25psi Front, 27psi Rear at my 200lb (Maxxis DHF/Aggressor or Dissector). Have yet to damage a rim or get a pinch flat. If sloppy and wet out, I might drop another psi or so. Granted I ride in the PNW and not where I have tons of square edge impacts with sharp and pointy rocks.

@bobohunter1776 3 года назад

I've got 2.5s and they look wimpy now. Even my little brothers fully rigid kids bike has 2.8s on it.

@chocofanatico 2 года назад

I run 16-17 psi on 2.60 tires on my e-MTB, tried a lot of pressures and that seems to work best. About 200 lbs total bike and rider.

@TheWeardale1 3 года назад

great video, i had no iea there was a minimum pressure limit on my tyres..!

@bikeradar 3 года назад

Thanks for watching! Enjoy the tyre pressure testing 👍

@b-horu7452 3 года назад

I run a 2.5 in the front and a 2.35 In the rear, both with cushcore. I run about 25 in the front and 30 in the rear so I don’t roll the tire or completely destroy it on Hucks to flat. I weigh about 190lbs.

@micego46 3 года назад

I’m 175lbs(80kg) and run 2.5 tires. I guess I’m a bit of an odd one out here as I always ride 30-32psi back and around 28psi front. I like the more firm feel for speed and 50% of the time I ride a lot of berms and jumps. I hate the feeling of the tire folding in the rear. If it’s wet I will take them to below 25psi. But it’s rare. Also I used to do motorcycle track days a lot. When a tire gets a slow leak and Corning at speeds and feeling the folding over feeling is super scary. So maybe there is just some psychological thing with me that I just hate that squirming rear feel.

@joelhenderson3723 3 года назад

There is a lot of variation, for sure. I'm 155lbs/70kg, and run pretty much the same psi as you, but on 26x2.25 tires. They also have tubes in them, which is another factor. I don't want flats, and I'd rather feel less sluggish than get just a hair more grip.

@kvmods 8 месяцев назад

Nice vest with the brown, where did you find that? :)

@joelhenderson3723 3 года назад

What was the internal rim on the 2.2 tires?

@richardmiddleton7770 2 года назад

Depends on tyre width, rim width, rider weight, terrain, tubed or tubeless, wet or dry, sus or rigid, what tyre it is, what day of the week it is....

@larrytate1657 Месяц назад

I like 35 on rear. 33 in front. As an over 200 pounder.

@krisby1 Год назад

crikey, I run in the 40s front and rear, I like the lesser rolling resistance and solidity. Last weekend I could feel the back was loose and discovered the rear was around 34psi. I do however weigh 104kg naked, so adding in clothes and whatnot then the bike is supporting a fair bit of weight. Yet to get a puncture thankfully. Interesting to see how little psi many of you run, even my partner at 59kg still runs high 30s, but we do run tubes too, perhaps we need to look at tubeless.

@JackMott 9 месяцев назад

Rolling resistance is worse at 40, not better. This is a common misconception, there is an optimum pressure, below which rolling resistance is worse because more energy is wasted deforming the tire, above that pressure is worse because you are bouncing around more. It is especially insidious because the higher pressures tend to "feel" faster, the bike "Feels" more responsive, but you are wasting more energy, and a stopwatch or powermeter can confirm this for you if you are skeptical.

@Rednax42 2 года назад

Oddly the tyres on my (cheap old) MTB are labelled "inflate to 50 psi" which is very hard - maybe suitable for road/tarmac? 28"x2.1" tyres

@Pienimusta 3 года назад

Pinch or press the tyre with your fingers. If it seems ok, it's good to go :D

@sambrown615 3 года назад

Wow. I’ve been running 50psi or near enough for long years and no problems.

@sambrown615 3 года назад

Should add they’re fat mountain bike tyres on roads. Off road I would reduce to 35 or 40. Oops 😂

@nebnollock5198 3 года назад

Jesus you poor soul, anything over 22 feels too harsh on the rough stuff for me lol

Boneshaker! 😬

@brasso9393 Год назад

40psi front n rear . But then again my ride and climb most of the road is asphalt. Even those hilly plantation are paved by the owners. Almost never need to deal with roots,rocks etc . Makes cleaning bike a boon.

@jeremysweeten2792 3 года назад

I bought the lie that “lower is better” and ruined two tires & a wheel.” No ones fault but my own; but, now I am 100% aware of mftr’s minimum recc. I’d rather “ping” than run flat!

Pirelli - hmm, just don't mention tyre failures in the WRC, and F1 the other weekend...

@ftrujillomunizaga 10 месяцев назад

If it's a "crazy think I'm gonna die" kind of dh track: as low as I can before I feel the tire fold and add +1 psi (usually 22 or 23 psi on 2.5" front and 27 psi on 2.4" 28 psi on 2.5" back). If it's a fun flow trail even less pressure as grip is all I care. When I'm having a shitty day and need to throw it all on the trails and not feeling like making smart decisions I just go full blown 28-30. At the ends it depends both on the trail and the mood 😂. General purpose do it all tire pressure: 22 front 26 back @80 kilos, no inserts 2.5" double ass combo 🍑🍑on a 30mm rim width.

@superwag634 3 месяца назад

@JogBird 3 года назад

its crasy that bike tyres cost more than car tyres, considering the material costs and huge safety reqyurement of car tyres

@franciswatson8793 3 года назад

What car tires are you buying? I've never seen mtb tires come anywhere near the price of a decent car tire. I guess if you are comparing top end mtb tires to cheap Chinese car tires then I guess they can get pretty close but is that really a fair comparison?

@tomaskonkol8894 3 года назад

@@franciswatson8793 my car tyre its Michelin CC 225/65/16 and cost roughly £90 fitted and balanced and last about 35-45k miles. Bike tyre no problem to spend £65 per tyre and will last 1.5k - 2k miles depending riding and surface. Check prices of moto tyres. Bicycle tyres are pure rip off in price.

@franciswatson8793 3 года назад

@@tomaskonkol8894 not sure where you bought your tire but I couldn't find a michelin tire in your tire size coming anywhere close to that low of a price where they used? Retread? Of course I'm using a online conversion and I live in the united states so pricing might be different. The cheapest tire I could find from michelin was around 110 pounds for a light truck tire and that wasn't even in the size you mentioned.
