I am going on my 3rd set of these tires at 140,000. They were the OEM tires on my '03 Tundra and both the original set and the replacement set have lasted almost exactly 70,000 miles each and I routinely haul a 7x14 dual axle box trailer full of dirt bikes. I could probably get a few thousand more out of the current set but winter is here and I am due for an inspection so... time for a new set. I doubt I will keep the truck long enough to wear out a 3rd set but I have to get them sooner or later anyway. I do not understand any of the negative remarks, in 140,000 miles on these tires I have suffered only one puncture and had the dealer patch it rather than replace it (they offered pro-rated replacement but I did not want mis-matched tires) and that was 40k ago and I have had no further problems. Great tires, monitor your pressure and rotate regularly like you should with any tire and they will offer plenty of great service. Probably the best tires I have ever owned.
