The A6 Radial from Hoosier is a Dry Racetrack & Autocross Only tire developed for drivers who compete in autocross, time trial and hillclimb events in dry conditions where responsiveness and high levels of grip are desirable. This particular Hoosier tire begins with a tread depth of 4.5/32" and does not require shaving for competition. However, it will benefit from a minimal scuff-in prior to its first run. It is important to note that Hoosier Racing Tires meet Department of Transportation requirements for marking and performance only and are not intended for highway use.
