A big improvement overall from the O.E. Goodyears, both in handling, noise and treadwear. They're very predictable in wet & dry weather, which is necessary on the Corvete. Road noise is quite a bit less than the Goodyears. I think I should be able to get 30,000 miles out of this set too. I needed an A/S tire and I don't think there's a better performance A/S tire out there.
