Any ideas on what tolerances you should put on recommended tyre pressure?
I have read some information (http://sheldonbrown.com/wheels)that manufacturers recommend slightly lower tyre pressures than ideal for liability reasons. This site recommends going up to 10% over the manufacturers recommendation.
I'd be interested in peoples experience on this?
I currently use Kenda 23-622 tyres for training where recommended pressure is 110 psi. However I realise other more expensive racing tyres have recommended pressures up to 220 psi.
I've been running Continental 3000 and Continental 3000 G.P. Supersonics over the past year or so, and because I'm a big guy, I always keep the tire pressure super high, in the 125-140 range (Supersonices recommend 140psi, while the 3000 recommend 120 psi).
It's killer on the streets of chicago, but anything less and I feel like im floating on beanbags.
I used to run max pressures or more, ie 125 psi on Conti GPs. However, now find 100 psi rides better, and doesn't seem to roll any slower for my 170 lbs. The sidewalls on the Mich Pro Race I'm running now say 87 psi min, 116 psi max....so 100 is right in.
Guess it comes down to rider weight and the road feel you like, but I'm sold on 100 psi..just my $.02.
