I love my michelin LTX M+S. (they make an AT version if you want more aggresive) I just got them and National Tire and BAttery will beat any price you bring them. They had to order my 225 75R15's cause they arent a size they keep in house. I was driving with GoodYear wranglers and the ride was terrible on road,the radio wasnt loud enough over the highway noise. Had to wear earplugs! Michelins don't require that I even turn up the radio from 10MPH to 70MPH.
The last set of these I had was on a GMC Z71, I used it on snowy trails and snowy roads often, and they drive great in snow. I got 93,000 miles out of them before I sold the truck and they still had 15,000 miles left on them. The tread wore evenly and I never rotated the tires. Ok maybe once. THe tires are expensive, but worth every penny if you want stock tires.
