Firestone Racing has brought more than 1,500 tires to the Chevrolet Detroit Grand Prix presented by Lear this weekend.
Each driver receives five sets of tur Black Primary tire.
Five sets of the Guayule green sidewall Alternate tire.
Five sets of the rain tire.
Cara Krstolic, Director of Race Tire Engineering and Manufacturing,
“The Firestone Firehawk race tires we brought for this year’s Detroit Grand Prix are the same design, construction, and compound as those we provide for all 2025 street races. The one difference from the 2024 Detroit race is the update we made to the compound on the alternate green sidewall (guayule rubber) tire which we expect will show some increased grip and wear. The drop off gap between the primary and alternate tire will be narrower than what we saw in the first two street races of the year. The characteristics of this street circuit with a mix of asphalt and grooved concrete make tire management a challenge for drivers, and tire degradation will likely be the main topic of conversation.”
