Race Tire vs. Street Tire. On a typical race weekend, a NASCAR Sprint Cup Series team will use between nine (9) and fourteen (14) sets of tires depending upon the length of the race and type of track - short track, speedway, superspeedway or road course. By comparison, an average set of street tires gets replaced approximately every three years. NASCAR Sprint Cup Series racing tire specifications also differ from race to race depending upon the degree of track banking and type of racing surface (asphalt, concrete, or mixture of both).
