I'm on my 2nd pair of Big O XT's and am very satisfied with them, the first went 52k before replacement and my current pair is at 35k. What I like is that I had a flat at 52k on my first set, took it in, and since I had not reached my wear indicators yet, they replaced the tire no questions asked. So I bought 3 more to match. They are a little stiffer than stock and the XT's are quite aggressive so they are a little louder than stock, but other wise no complaints. I will probably get a third set before next winter.
