The Firestone Firehawk guayule race tire will make its on-track debut this weekend at the Big Machine Music City Grand Prix on the streets of Nashville, another milestone in the efforts of Firestone and the NTT INDYCAR SERIES to promote sustainability. The guayule natural rubber is located within the Firestone Firehawk’s sidewall. Bridgestone race tire engineers decided to use the guayule rubber in the entire sidewall because that area is made up of the most natural rubber. Bridgestone plans to incorporate guayule natural rubber into more of its race tires starting in 2023. That effort will begin with using guayule rubber at multiple Firestone tire tests throughout the year to see how its use can be expanded for the 2023 race season. The racing debut of the guayule tire is an important step in a journey that started 10 years ago for Bridgestone. In 2012, the company launched a guayule research initiative aimed at diversifying the world’s natural rubber supply. Bridgestone aims to commercialize use of guayule rubber in tires by 2030 and will continue to improve guayule productivity through sustainable methods.
