My plan is to run Hoosier Quick Time bias ply DOT 16.5x31 for the street ride cause they have lots of tread in case of rain. And then switch to 315 pro radial on 15x12 rims if money allows. Obviously with a big offset in the rims. The smaller 29 Dia radial will bring up my race rpm a little, so the mild gears I run should make them about right for racing with the smaller radials. The 16x31's are actually small for my car already...
Never had a set, but they say leaf spring cars run well with them, so maybe we learn somthing in switching.
I should clarify - you don't need to run radials, it just can't be a regular DOT tire. It can be a drag radial or a conventional bias ply DOT or track only slick, just no street tires so the tread doesn't screw up the track prep. QT Pros, ET Streets, ET Drags, etc are all okay, either bias or radial. There is a width restriction on many of the classes though.
