Kirk,
Are you talking about a '93 Mustang? If so, doesn't that car weigh like
3300 lbs. with more than half over the front wheels? So we're talking
about cars that are roughly 1,000 lbs. lighter with close to 50/50
distribution. I would expect lower pressures, but how much lower?
James, your pressures seem low even for your light car. But maybe I
should try it. The treadwear goes all the way to the sidewall corner but
not over. So maybe I can go even lower?!? At that low pressure I'm
afraid of damaging the rims. Maybe I shouldn't worry about that until
the treadwear starts coming over the corner of the tire.
On my 2850 lb. RX-7, using V700s, I got the best sticktion at 30 F / 28
R. Using R1s on that car, the sweet spot was 29 / 27.
