they only lasted 45000 miles. I replaced them with BFGoodrich - Long Trail T/A® Tour from BJ's. Unfortunately, the jerk who put them on didn't tighten one of the valve stem cores, causing it to leak if I took the cap off. Rather than bring it back, I bought a wrench at Autozone (around $5) and made sure they were all tight. It seems that I took a hit in MPG, but the traction/grip of this tire is much better, plus there's a 60000 mile guarantee. I recently inflated all the tires to 37 psi (the max on the treadwall is 44), so we'll see if that helps my fuel mileage.
