The brand that supplies the rubber we race on, Firestone has been the sole tire supplier to the NTT INDYCAR SERIES for the last 23 years.

Ever since Ray Harroun’s Firestone-equipped Marmon Wasp won the inaugural INDY 500 in 1911, Firestone has worked tirelessly to evolve race tire technology.

In 2022, Firestone broke new ground as it introduced its first sustainable race tire made from domestically grown guayule-derived natural rubber, featured in its alternate tire’s green sidewall.

The tire, which has a green sidewall, was developed as part of parent company Bridgestone’s efforts to achieve carbon neutrality and to manufacture tires from 100% renewable materials by 2050.
