I have no complaints at all about my lt4 xc tires. I have 74000 + miles on them, they still have plenty of tread left. After 8 years of owning them the side walls have a few small dry rot cracks in two of the four tires. I would bet they would be fine for another 20000 or so miles, but I am going to make a long trip and plan to replace them with exactly the same tires before I go. These tires are worth the money.
