What tyre pressures do you run?

Noodoo · June 2007

What tyre pressures do people run for XC use?

I was running between 20 and 25 psi, but having pumped them up a lot more the other day, I noticed that they now offer a lot less rolling resistance (obvious really), So I was wondering if there was a rule of thumb about tyre pressures that I'm not aware of....

i go for about 30 psi. althoguh ive got a mate that runs his at 60 psi so its all down to preference. i like a bit of give at the back as im on a hardtail.

About 35ish on a full susser. Anything less then that and i don't like cornering.

i would have mine at 40psi on my hardtail, although i am more inclined to all mountain that xc

ddoogie · June 2007

I run about 40 on front and 45 on the back on my full suss. You don't need the extra grip from low pressures when you have 5" of it at the back and front. On the hardtail its about 30

hmm...looks like i run my pressure higher than most on my ht

JinjaNinja · June 2007

Like said, each to there own, and to a certain degree the track too! Localy I ride with fairly low pressure as its absolutly covered in jaged rocks, roots etc...

Who me · June 2007

FS - 40 PSI
HT - 30 PSI
SS Rigid - 40+ hate getting punctures on this as they are a biatch to fix

pete13 · June 2007

ht 45-50
fs 50-55

mmm_pie · June 2007

For XC rigid I go for the max 65PSI. Rather uncomfortable but lots of speed.

Sometimes it overheats. You have to make sure it's in a ventilated place all the time.

cyclone · June 2007

On my FS:
40psi - Smooth XC - Nice and fast
35psi - Rough XC - Not so fast but more grip
30psi - AM - A little bit of drag but loads of grip on roots and rocks.

55psi on my HT but mainly use it for commuting and bridle paths.

KeelKlein · June 2007

75psi all round on a hard tail, makes it fast and loose & I don't seem to suffer from "Snake Bite" punctures.

inthegrip70 · June 2007

I used to go for for about 70+psi, but running that on a hardtail at all shock absorbant.

Now im around 45psi front and 55psi rear

HappyZZZCamper · June 2007

Between 50 and 60psi on my hardtail. Gives a much bumpier ride on the trails, but it makes getting to the trails that much more bearable. Also, since using high pressures, I have yet to get a snake bite puncture, despite failed attempts at hopping over gnarl.

45psi front and 40psi rear, hardtail or full sus.

depends on the tyres

40-50psi for a semi slick tyre, bit higher at the frnt as there is suspension

Only the truth hurts, but thats more than enough.

RetroYetiRigid · June 2007

Between 50 and 65 psi front and rear. Don't have a problem with snake bites at that pressure.

I did roll a rear tyre off the rim with 40 psi in it once hence the higher pressures now.

chilled rider · June 2007

I ride a hardtail and i run my tyres as hard as i can get. Last time out i had front softer than usual and had tyre come off rim. Thats probably the only time i did that so its back to rock hard tyres for me. As for pressure's 'Rock hard = no punctures & less drag'

I usually ride the front at about 55-60 and the back at about 45-50. My new wheels say that they should be run at 59 though.

hsa · July 2007

Been running my XTC at 40psi F&R. Surprised by some of the pressures posted here. I may try upping it a bit, then!

dunnnooo · July 2007

So I'm the only one who simply keeps them 'pretty solid' by the thumb test?

supersonic · July 2007

I just squeeze them. If they feel ok, I ride!

bigdawg · July 2007

Ive noticed the newer xc tyres have a lot higher pressures on the side of the tyres than they used to 40-60 instead of 30-40 (back in the day

)

Racing last night I tried to only put about 40 in (lower end of the scale) as there were loads of d/hill off camber rooty hairpins, but im guessing the guage on my pump is way out, as there was def more than 40 in there...anyone know of a reliable guage for skinny valves??

Sharker69 · July 2007

I have a hardtail and run:
55 psi roads
anywhere else 35 front and 40 on the rear

Ticaboy · July 2007

50psi regardless.

ivancarlos · July 2007

55psi hardtail 2.2 tyres

Jaba666 · July 2007

It depends on what tyres I'm using, but as XC is all about speed and rolling resistance drops the higher the pressure..... therefore

I run approx 5psi below max on the rear and 15psi below max at the front.

What tyre pressures do you run?
