Replaced original Michelins on my Ford Explorer 4X4 @ 24K with 1st set of Kumho's. They lasted 29K and replaced them with a second set of Kumho's which now have 27K and have 5/32 tread left. I've always been pleased with quietness and handling but not with length of wear. Always rotated, pressure checked and 4 wheel alignment. There is no way that these tires could last anywhere near the 85K as advertised. Kumho got me for two sets of tires but they will never get me to by any tires in the future.
