How many miles did you get from your Michelin Energy Savers tires and What tire pressure did you use? I have gone through 3 sets with total mileage of 213k miles. Michelin Energy Savers AS are warrantied for 55k miles and at 50 psi I got 64.5k and 64k miles out of my first two sets which weren't worn down to the 2/32", I replaced them because I was going on long trips in snowy conditions and wanted max tread. My third set I replaced the fronts at 78k because of puncture in sidewall. They could gone probably 3k more miles anyways. The rears I moved to the front and they currently have 85k miles and looks like they will make 90k mile unless I have to go on trip in snowy conditions.
