Didn't vote. Been setting my pressures on everything I've owned for the past 20 years by pyrometer. Only way to get it exactly right for any car/driver/tire combination IMCO.
I use 46 cold and gain about 3 psi when hot. We have low humidity air here.
Like you shmoky, I have 255/60 T/As front & rear. The sticker on the door of a '76 says 20 psi front and 26 rear cold. Back in the day I ran all four around 30-32. But now that I'm an old fart I've found that 22 front & 28 rear seems to feel just right.......
Glad to see this post, I have been running the 20/26 on my 76 as I thought you were supposed to follow the door label.
I thought by 76, they were putting radials on the Corvette and so these recommended pressures were for a radial???
I think I will try the chaulk or tape method and add some air!
(Maybe I am giving my new Bilstein shocks too much credit for ride comfort!!)
