I have 2 pairs of Hoosier Tires from the IKF Grand Nationals for sale. They were the spec tire and we do not run them in any Northwest Races. Each set was used for 2 practice sessions, 1 qualifying, 1 Heat Race and a final in World Formula and LO206 Classes. More than half the tire life left on tires. $50 a set of 4 or $100 for both sets.
