What air pressure should I run in old bias-ply tires on a 1970 Chevelle SS for cruising? These are old originals not reproductions if that makes any difference. Thanks.

Assuming that your Laramie's are considered suitable replacements for the stock tires in 1970, it should be what is on the tire inflation sticker: 26 cold f/r as I recall (single passenger).

I'm running 28-30 in my Chevelle and the Nova. Both cars are running repro Bias F-70s and they seem to be wearing fairly even.

I had a set of ProTracs on the Chevelle earlier. I ran 32 in the fronts (215-70-14s) and 24 in the rears (275-60-14). Same thing; fairly even wear pattern. <<GRAEMLIN_URL>>/dunno.gif

My method on a hi-perf car: Run the max recommended pressure that's printed on the sidewall of the front tires. For the rear, find a clean patch of pavement and adjust pressure for a FULL &amp; EVEN width contact patch when they spin. Simple <<GRAEMLIN_URL>>/3gears.gif

Great, thanks guys! I've got 30 psi in them and they feel pretty good going down the road but I wanted to make sure. The original tire inflation sticker is loooooong gone.
