I installed a full set of 4 Michelin LTX M/S2 on our 03 Sport last month. Michelin had/has a $70 mail-in rebate going on and I received my $70 rewards card last week. Back in Oct 2007 I put a set of 4 Michelin LTX M/S tires on at 75,000 miles. When I replaced those last month mileage was roughly 160,000. Thats 85,000 miles on them over 7 years. Most of my driving is highway driving between DE and east coast Canada. The M/S tires were great in ALL driving conditions from hot summer days, rain, deep snow in Canada as well as some light off roading to a few remote campsites up there. I found a thick knife blade one morning in one of them a few years ago (grumble) and had it replaced. I had the original unused spare tire from 03 removed and this newer M/S put on for safety when I had the new ones installed last month. The M/S2s are a bit softer and thus just a tad quieter on the highway though barely noticeable. I hope I get the same great use out of these!
Since the M/S2s went on I've put about 4k miles on them and so far I like them just as much as the past M/S tires. If you're looking for a replacement tire or set I'd recommend them for sure.
