IndyCar has announced multiple updates to rules regarding use of the official Firestone tires for the upcoming 2025 season.

[…]
For street and road course events, each entry will receive a total of 10 sets of tires, with adjustments in the number of primary and alternate tires. The allocation now includes five sets of softer, alternate compound tires and five sets of harder compound tires. This change allows drivers to utilize the softer tires earlier in the weekend rather than only during qualifying and the race. The exceptions to these adjusted allocations are at The Thermal Club and the Indianapolis road course. Both tire compounds must be used during each race, leading to varied strategic decisions. Additionally, the split practice sessions will be expanded this season to all road courses except for Road America, promoting more running early in the weekend. The new tire rules will be tested at the upcoming season opener in St. Petersburg, marking the beginning of the 2025 season.
