[B]Krazik, we've been down this route before in many other threads. In Australia before you are allowed out on the track for a high performance driving day the school owners will insist that you pump the tyres up to manufacturers recommended presure (32psi) + at least an additional 10% (3.2psi) = 35psi COLD. They do this in order that they don't have their students sliding off the track and wrecking their vehicles.

 

Krazik, I agree with UL that this should go to a different forum. In my post I was referring to a racing school not a driver school. I stand by my orginal position. For the first 6 months of my S02 useage I ran lower pressures (around 32-33psi) when I checked the tyres it was clear that there was wear on the outside of the tread whilst the centre sections were relatively unworn - a clear indication of under inflation. Once I pumped them up a little harder I started to see even wear and left them inflated this high for the remainder of their life. You also need to consider that with body roll under cornering you are going to have more tread on the road with higher pressures, even if in a straight line there is less.
