I put these tires on my car at 51k and now have 146,225. I still have enough tread left to pass inspection but the wear has degraded performance and handling. Maybe these were a fluke becuase I have never had a set of tire last this long and will definitely buy these tires again. I live in the northeast and have driven these tires in every weather condition and must say I have never felt more confident in my cars ability, safety and performance. I used to run Goodyear RSA's (very expensive) They were a very good tire but could only get 35k at the most out of them and they were noisy.
