I ran 2 sets of Michelin LT tires (not sure of the exact style) on my '93 Grand Cherokee LTD that I got rid of in '03 - 40,000 miles on each set. They replaced the OEM Good Years that came with the Jeep after only 20,000 miles on them.
Only reason I replaced the first set @ 40,000 miles was because the sidewalls developed cracks. I never had any other problems with them at all; I just couldn't take a chance that a blowout would happen while the family was in the vehicle. When I got rid of it the 2nd set started to show signs of cracking too, but there was plenty of thread-life left.
Before I bought the tires I was told by several people that the Michelin's sidewalls were prone to cracking - I don't know if that's the case now-a-days. In any event, I would by Michelin tires in a heartbeat!
