Radials will be faster than bias ply, but they are more sensitive to track conditions. In other words, they will spin easier and worse if track conditions aren't good. Naturally, how well your suspension works to begin with is a big factor.


I've also heard that a taller tire will hook better than a shorter tire. Actually puts a bit more rubber on the track. Height is usually selected based on rpm rather than hook.


I've been running Hoosier radials exclusively for many years with great results. Never made a comparison between them and their biased ply for specific ET gain and life expectancy.


Use a rim at least as wide as the tread to allow for higher air pressures and better footprint.
