I have a set of T30 Evo's. A bit too early to speak about mileage. I have about 3k km's on mine of fully loaded touring and starting to show a bit of a flat spot on the rear. For reference, my last Shinko 705 rear lasted 7k km's. If I get 10k km's on the rear, I'll be happy.
Besides mileage, I love these tires.
The only other tires I've had on my Wee have been 705's, and the T30's are infinitely better as a road tire. The bike just corners so much better than the 705's, I can't believe it took me so long to switch.
PS, I paid $300 taxes in from Pete's Superbike, Bridgestone has an additional $50 mail in rebate.
