Compared to the tires used for cars you see on the street -- and drive yourself -- racing tires are designed by Goodyear specifically for the NASCAR circuit.
Racing tires have an average life of 150 miles, although that varies greatly with circumstances such as track length and pit strategy.
With tread thickness at 1/8 of an inch and a weight of 24 pounds, teams generally use between nine and 14 sets of tires per race.
With a mind on safety, the Goodyear Lifeguard Inner Liner Safety Spare -- a tire-within-a-tire concept -- is used on oval tracks greater than one mile in length, and also on the right-side tires at Bristol Motor Speedway. It features a separate valve system that prevents the tire from becoming unbalanced.
