Indy 500 Tires Feature Recycled Plastics in Rubber Compound

The 107th Running of the Indianapolis 500 presented by Gainbridge has another small element that is another step toward a big impact, and it comes courtesy of a collaboration between Firestone and Shell. This specific updated tire also was used during last month’s Open Test at Indianapolis Motor Speedway. “It’s been something that we’ve been really proud of being able to put into our race tires,” she said. Krstolic also provided some insight into Firestone’s guayule tire, an eco-friendly natural rubber compound derived from the guayule shrub and used in the alternate tire at each of the street circuit events this season. The guayule tire debuted last year at the Music City Grand Prix in Nashville, the only race where it was used in 2022. This year’s race total for the tire has increased to the five street races, but it still will be some time before guayule is used in the construction of the tires at every round.
