I don't know why there are so many mileage discrepencies with this tire. I rotate and balance this tire every 6000 miles and keep about 36 PSI in them and I have over 67000 miles on them with 7/32 tread left on them. They are great in rain or shine. They don't seem to hydroplane. They are not overly noisy or stiff. In the snow they are only so-so. But on ice last winter I had to go up this hill on the way home that was like a skating rink. Semis and other cars were just spinning and I also saw a few other 4 wheel drive vehicles spinning, but my tripletreds just walked around everyone and got me home safely. I will probably replace them next year with the same even though they are quite pricey. Overall a great all season tire.
