what is the best tire pressure you guys use at the races for your stock tires on camaro 16" (P245 ZR50)

thanks

...Find a fresh asphalted stretch of roadway and do some 'tire testing'. This is true for ANY type of tire, street or drag.

Maybe start out around 30#'s of air in each. Do a short burnout. Get out and look at the contact patch. Next go down or up depending on the results/looks of the contact patch.

Key:

1) A thin patch left on the pavement means TOO much air, reduce pressure accordingly.
2) 2 dark lines for each tire means TOO little air pressure, increase pressure.

You are after the full contact patch from the tire. You might even take along a measuring tool to measure tire surface area AND tire contact patch area on the pavement. You will be looking to get as wide and dark of a contact patch as possible.

Good Luck!

Redbird,
Thanks for your reply and your other post as well. Testing different pressures on a strech of empty road is definiatley a good idea!

on my BFG's i use around 25-28 psi and they hook up well. considering that i have almost no tires left they perform well with that pressure.
