On a typical race weekend, a Cup Series team will use between nine and 14 sets of tires depending upon the length of the race and type of track. By comparison, an average set of street tires gets replaced approximately every three years.

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).

Goodyear uses about 18 different types of tires to cover the needs of teams during the course of a racing season.
