Notes from Cara Krstolic: This year’s Firestone Firehawk Indy 500 tires have the same race-proven construction and compound design as last year. This year, it has slightly softer compounds with added grip. In keeping with our sustainability efforts, the tread of all our 2023 Firestone Firehawk Indy 500 tires also incorporate a synthetic rubber created with ISCC+ certified recycled Butadiene, a monomer produced with recycled post-consumer plastic waste, that was developed in partnership with Shell.
