That would be a good thread.It would be nice to have a survey of how long the different tires types and sizes are last on these TM3s. With the extra weight, and extra instant torque, I would surmise most people are getting less than rated mileage out of their tires. My bet is you are on the low side at 18k, but not outside the bell curve just yet.
I called Michelin regarding their warranty claim on these tires. And sadly, the rep could not locate a local Michelin shop nor did I ever receive a return email or call to schedule a courtesy tire inspection. So in essence, Michelin's warranty is totally bogus.
I would definitely like to see some other examples of other tire types and performance.
