Not Ranked
As I recall I ran about 22psi in mine. Look at the tread to see whether it's all contacting the ground. They will plump up in the middle of the tread with too much pressure, as mentioned. I was careful to square the rear end in the chassis, as mentioned. I also ran minimal camber... less than 1/2 degree. Pretty sure I ran about 1/8 toe in, caster was about 4.5 - 5. Toe and camber ideas came from searching around and reading guys talk about bias ply tire settings. "They don't like camber." The caster wasn't as heavy as I expected with manual steering given the width of the front tire (was running a 275 width front tire previously).
I would have played with more suspension settings if it was easier to adjust the rear, and if I hadn't sold the car. Making the rear arms more easily adjustable is on the list for the new car.
