Default Tire pressure

I bought my '94 a few months ago. The previous owner put on Goodyear Aquatreads. I had a rebalance done on them and the shop guy said to run 40 psi in them cause low profile tires need that kind of pressure. The car handles and rides well enough with the 40 psi. It's a DD and not a racer. What's the right range?

32-35psi COLD.

40 is too much.

I run my Michelins 285R40 17's at all four corners at 32lbs. I can not imagine how bad my 94 would ride at that pressure. I do not believe I have heard anyone running that high pressure for street use on a 94 Corvette

Well 40psi is like the max inflation of the tire used for mounting them and will make the car ride like a Flintstome mobile.

Try 35-37psi up front and 32-33psi out back.

It depends on the tire but 40psi is just too much for any tire on a Vette. I watch my tire wear and adjust the pressure as necessary. I run Michelin Pilot Sport A/S and over the years I've found 30psi front 28psi rear gives me the best wear.

Default I use.....

35 all the way around. It handles well and the wear is great. Best of all it cuts down on that tire noise. Give it a try.

You have to experiment for your car, but I do lower mine to below 30 in the rear, sometimes I play with the front. sometimes I leave it alone.
