The R6 from Hoosier Racing Tire is a D.O.T. rated Track & Competition tire developed for drivers who compete in road racing where responsiveness and high levels of grip in dry conditions is desirable. The R6 Radials are designed to provide performance advantages over previous R3S05 tires by rewarding drivers with faster, consistent lap times and extended wear due to the improved traction and handling. While the R6 Radials use the same successful tread compound as the R3S05 tires, it is molded onto a more rounded tread profile that extends the life of the shoulders and produces more consistent tread wear across the entire contact patch.
