Newgarden is passionate about IndyCar in Nashville and last year packed his schedule with pre-race appearances to promote the event debut. The guayule natural rubber is located within the 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. This allows Firestone to maintain the same quality and performance as the existing race tire. Bridgestone plans to incorporate guayule natural rubber into more of its race tires starting in 2023.
