Front tires

Been running radial fronts with bias slicks since before riverside international raceway closed. That was in 1989.
Edit: with regard to flyfishes comment in post#7, he is absolutely right, bias tires can get squrrelly on the big end (regardless of front tires!), If run with a little too low air pressure, in order to get the car hooked up at the starting line. The stiffer sidewalls of a radial tire ARE much more stable, and partially because they work better with more air in them than bias slicks.
