Firestone Racing has confirmed that there will be a new primary compound for this weekend’s Sonsio Grand Prix on the Indianapolis Motor Speedway road course. The construction of the Primary and red-walled Alternate tire are the same as the ones used at this event in 2023 and for 2024, Firestone are bringing more than 1,400 tires to the Grand Prix of Indianapolis.

Cory Williams, Principal Program Engineer, on INDYCAR tires:

The Firestone Firehawk primary tire and alternate (red sidewall) tires have the same construction as those supplied for the 2023 IMS road course. However, there is a new primary compound for this year’s race that falls between the compounds provided at last year’s Mid-Ohio and IMS road courses, providing a slight decrease in grip and wear. The compound on the alternate tire is the same that was provided for the 2023 (Fall) Gallagher Grand Prix (IMS road course race).

Each NTT INDYCAR SERIES entry will receive the following allocation:
Primary (black): 5 sets per entry*
Alternate (red): 4 sets per entry
Rain (gray): 5 sets per entry
*Rookies receive an extra set for Practice 1
