hi again,

what pressures should i be running, i got 10-15psi at the moment, thanks

No more than 4 PSI rear, about 6 or 7 PSI front.

With Michelin's 4 psi back and 5.5psi front unless you are very light or riding very muddy sections with no rocks. Check a few times especially if the weather is cold and sunny. A back tire can go up a pound after being first checked on a spring morning.

A good low pressure tire guage is money well spent.

Good advice.

thanks for asking greenlaner1

tyre pressures was gonna be my next question

wow, as low as that??

i would have though that the lighter a person is the higher the pressure must be? thats why i was running about 10psi, i weigh in at 15stone

cheers again

Yer a fat git like me, run the rear at anything between 3 and 5 psi depending on the gloop to rock ratio

Yea, me too. I weigh about the same (hmmmm, 1 stone equals 14 pounds?) and I usually run 4 rear, 6 front under most circumstances. I may run 5 rear if there are sharp-edged rocks and 3 if it's sloppy wet but no nasty sharp thingies.

You'll want to get a good tire gauge, you will use it a LOT in Trials and try to get one that has a low range (like a 1-15 psi range here in the States) because most gauges have a percentage of calibration inaccuracy, generally about 2-3% which, for instance would be 2-3 psi for a 1-100 psi gauge (not good for Trials) but that would only be about .30-.45 psi for a 1-15 psi gauge.

As an old git in a digital world i never measure my tyre pressures with a guage I just sit on the bike and adjust visually a new Michelin on a cold day would be chalk to cheese of a used (especially down the road and get some heat through them) IRC for example. Of course you must also conder where and what you are riding... Horses for courses!

As an addition to that, the best gauges I found were from a company that sells supplies to serious dragracers. Tire pressures are important business in dragracing, where a pound of pressure can make a difference. I bought a Longacre 0-30 large dial gauge years back and at the time the price made me gulp a little, but it's been bulletproof, extremely rugged and I've had it calibrated several times and it's been spot-on every time. So, in the long run it was a bargain.

nice one guys, will be getting me a tyre guage

hopefully will have my first proper ride on it tomorrow, if it isnt raining (fingers crossed)
