I have had 3 sets of michelins on my tow vehicles over my lifetime. None made it over 30,000 miles. They never wore much but everyone got weather checks in them so bad I replaced them. The tires I run now have about 60% tread left at 24,000 miles. The michelins were load range E a highway tread. The ones I have on now are cooper load range E kind of a radical all season tire. I will say I'm kind of hard on tires. To much speed & weight I guess. If I can get 40,000 out this set I'll be well satisfied.
