It s been quite a few years ago since I went from Bias to radial. When I made the switch I made two run with the radials and took them off. They were ill handling. I put bias back on and ran it that way for several more races. I was forced to put the radials back on the car one day due to getting a flat. I put the same air pressure in the radial as in the bias and the next pass was 0.13 faster than with the bias tires and handled perfectly. Both times I tested this the result was the same . Since then I run the radials all of the time and run them about 13 psi.
This is a super stock car and I run the Hoosier 13.5 x 31.5 radial
