Wow, that's a lot of miles. I must drive like a maniac! Actually, I do drive fairly fast and spend lots of time on winding mountains roads. And my 3/4 ton Suburban is pretty heavy I guess. My only complaint about Michelin LTX-MS/265-75-LRE's had always been that I had to replace them after 50k miles. Granted there was a little tread left, but the wear bars were starting to come out, which isolates the center tread and gives water no place to pump out towards the sides.
But it's a great tire and has served my family well. No complaints that would make me change tires, though I have had a couple of people give me recommendations for alternatives that I've been considering.
The 105 K was on a 1990 Chevy Caprice. Last of the square big Chevys and a comforable car for long distances. It was a little questionable in Minnesota snow and ice, tho...
