The Hoosier R7 DOT radial was specifically designed to provide a level consistent grip with good wear characteristics on dry tracks beyond the capabilities of traditional passenger car tires for drivers to compete in Autocross, Time Trial, and Track Day events. The internal structure of the R7 features a symmetric construction that uses two lightweight steel belts reinforced by a spirally wrapped circumferential nylon cap ply under the tread on top of two nylon cord casing plies. It features a rim recess design on all sizes & its symmetric tread design and internal construction allows the tire to be mounted on either side of the car (and later be remounted inside out to further extend its life). The tread is molded in to a racing slick based design at a depth of 4/32 which removes the need to shave the R7 for competition Hoosier DOT-radials typically have very generous unmounted dimensions, so be sure to mount on appropriate-width wheels before making any judgment related to physical size. The section width, tread width and shoulder profile affect the clearance between the tire and suspension components and/or body panels. If the intended application is an aggressive fitment with close tolerances, it is recommended to test fit a mounted, inflated tire to check for potential contact between the tire and vehicle before driving on the tires.
