I've got about 47,000 mile on them now, got a price on the Michelin Energy Saver A/S today with the $70 rebate. I'm talking to dealer through email, wanting to make sure they are A/S tires that have the 65K mileage rating instead of theMichelin Energy Saver that only has 50k mileage rating. I didn't know there was two styles until I looked it up. Had my 2011 1 year 4 month now. I could probably get 50K miles out of tires. The gas mileage has increased to 53-54 mpg at pump tank after tank. I guess the 2 or 3 mile increase is due to the wear on the tires?
