We ran 32 psi in the original Goodyears in the '70s, Fire. I assume you have repros. Those things are going to ride hard at any psi compared to modern radials. The bias-plies just won't give and flex like a radial. But on the bright side, no radial has the handsome sidewall profile of a Wide Tread GT, nor the classic lettering and tread design. In their day, Goodyear Wide Tread GTs were THE tire to have! Wish I could lay my hands on a couple of L-60 14s now.....
