    "Tires Designed for Champions"

    The Hoosier Sports Car Road Race and AutoCross Radial Tires are designed specifically for sports car racing classes that require a DOT (Department of Transportation) legal radial tire for competition use. The Road Race specific R7 and Autocross specific A7 compounds have been developed to increase consistency and wear without sacrificing performance. An increase in performance can be expected over competitive brand and previous versions of Hoosier racing tire compounds when these tires are broken in and used as specified.
