tire pressure
Hi all,
Can't seem to find the tire pressure recommendations no where on the Vett or the manual. Know its 35psi for over 150mph but not for everyday driving.
Thanks

Tire pressure
I have a 1984 with the Z51 performance suspension. The recommended pressure is 35 PS I. However I have read that the Z51 had such a hard ride that Chevy issued a bulletin that 24 PSI was OK if the possibly increased or uneven tire wear was acceptable to the owner. I have also come across the opinion that the 35 PSI figure had a lot to do with the cars fuel mileage. I usually run 30 PSI which works fine for me. My tires are new but the car needs rear bushings, etc so its handling is not that great so I could probably run any tire pressure and not notice much difference. I have run 24 which felt fine, too but I was worried about wear.

Starting with the '94 model year, stock tire pressures were lowered from 35psi to 30psi to improve ride quality.
If there is no sticker on the driver's door, somebody removed it. That sticker would also show the specific tire size for the car, based on suspension options, and the maximum cargo weight that can be carried (including the driver).
You can adjust the tire pressure for what you feel is the best for handling or ride comfort. I would not go above 35psi for street use. Tire pressure for autocross and track days can be different based on the tire itself, the air temps, alignment, and pavement temps.
As the tire heats up, the tire pressure will increase.
