What width rim do you have them mounted on? That will effect the contact patch.

I ran mine between 12 and 13.5 depending on the track. Never had any luck lower or higher. 10 inch wide rim.

Depends on the track conditions. I've taken wrinkle walls down as far as 7 psi. I've ran radials with as much as 17 psi. Just depends, there is no right answer.

I run my 28 x 10.5 stiff sidewall on a 15 x 8 rim at 15-15.5 psi on my 3600 lb Nova. I don't run anymore than this b/c it will wear out the centers before the sides. You want to run as much air as possible with a consistent hook, and the more weight you run, the higher pressure you should run (keeps the sidewall from wearing out faster than the tread).

What is the power level/times on the car?

Should be fine in the 13 to 14 psi range
