The car is a 996TT, not sure what cold air pressures to start with and what hot air pressures I should run then at. Can anyone point me in the right direction. Thanks.

snook...

40 hot?

generally speaking....tires will expand by 5-10 lbs....so use 7 as a starting point..

start them at 33 cold.....run a session....check pressures immediately after pulling off track..

at least its a start.

You might want to be a little higher than 40 hot. 42 might work a little better.

Id start at around 35

What run group are you in? What is a track and the air temps?

Generally R-Comp tires get greasy over 40psi hot. A lot of them like to be at 34-38 hot...depends on the car and set up.

For me in my 09 Carrera S with R888's at Sebring I start out at 28 and after the 1st session I am at 38. However as the day heats up I bleed air from there. The next morning cold I am usually around 26.

38-40 front, 40-43 rear is what I shoot for.

Finally got to the track after sorting some issues with my car. I played around with the tire pressures in the morning and settled on 36F/38R hot. The AD08 tires handle good and had decent grip, their definitely not as sticky as R compounds but they are suppose to be good in wet conditions and you can drive to and from the track without any problems.

What R compounds did you used to run? I trying to get an idea of how AD08's compare.

MPC on a M3. The ADO8 is suppose to have the grip level somewhere in between a street tire and a R compound. Imo I find them to be closer to a street compound.
