As has already been touched on...... the bias plys don't run as much pressure as radials. BFG had a formula for calculating a pressure but I will be darned if I can find it now. With me and fuel my car is 45/55 split, 2730 pounds. Seem to me the formula said 24 front 26 rear. I run more in the 20-22 pound range in the front and 22-24 in the rear. For competition, need a tire pyrometer (not the infrared type). Most of the buys busting tires are to young to even remember passenger car bias plys!
