i have a 99 z28 conv, but i have 17" rims with 245 tires.
was wondering what tire pressure should i use ?
rear and front ?

thanks in advance,
Shay

 

Depends on the tire..

Check the sidewall and see what it says

 

i have 245/16/z-rated at 32 psi front/rear

 

is that on the door ? the tires aren't stock tires, i installed 17" rims and new tires (the Z comes with 16")
thanks

 

the side wall of the tire

 

The psi for a cold tire is generally 30psi for a passenger car. That's how it is on the Vettes, the Camaros, the Cadillacs, etc. But just to be safe, make sure you're within the range listed on the side of the tire.
