What is for best tire pressure range for our cars, on an autoX track?

Depends on what kind of suspension and tires you have. Give us those details first.

If you are running a stock suspension set-up on stock tires, usually just under the Max tire preassure that is written on the sidewall.

I run Falken Azenis for Autocross and I usually run between 33-39 lbs of preassure - Depending upon the track conditions and the track type. Remember, when you race, the tire preassure will increase as the tire heats up, up to a couple of pounds.

Thanks for the info. Right now my car is completely stock, but I'm going to start modifying it next year. I know what you mean about the tire pressure increasing with heat. I heard some guy say that if the tire is filled with nitrogen it won't expand nearly as much, is that true?

I would start with about 45-50psi in the front and 50-55psi in the rear to help compensate for understeer.

I agree, BUT still check the max PSI that the tire recomends on the sidewall and subtract approximately 3-5 lbs, as I stated before, the preassure will increase as the tire heats up.
