If your tires are very old, a change to a "newer" bias-ply repro tire would probably help you. After the tires experience so many heat cycles, the rubber in them goes to crap. Pete can attest to this as his '70 COPO Nova has NOS Polyglass tires on it, and he said they were pretty much useless when compared to the "newer" repro Polyglass.

On our Camaro, we are running around 44 psi in the rear, and about 46 psi in the front. The key is to make sure your black marks are even all the way across, which means your tires aren't cupping or overinflated. Pumping the fronts up is supposed to decrease rolling resistance.

It's not just the "old" Polyglass tires that are a little wild on the road. Our repros do the same thing...I guess it's just the nature of the beast!
