I got about 8,800 miles out of the original equipment Bridgestone Potenzas and about 14,000 miles out of the Firestone Indy 500s which replaced them. This was street driving, pushing it hard when I can, no tracking.I checked the tire pressures every 3 or 4 weeks, and also rotate my tires about every 4,000 mi as
@Alkoran said above.
I'm satisfied with that amount of mileage, given that these are soft compound summer tires which have a higher level of grip. I wouldn't want to get harder compound tires and lose the grip and good handling just to get some more mileage out of them. On the ST version, I feel like that would just defeat the purpose of the car.
