Your question is what if you use bias tires on a automatic car, right? My experience is you will lose one tenth in et. Second, the air pressure will be lower. How much lower you would have to test. In the past you wanted to wrinkle the side wall in a bias tire and not wrinkle the side wall in a radial. I run 18 to 24#'s in my radials. Anything lower and they stop working. I would think the bias would be 18# and lower until it hooks right.
