I rotate, align and keep tires inflated religiously. My Toy 4R currently has 228,000 miles on it and this is the SECOND set of tires I have owned! The Dunlops that came on the vehicle at purchase lasted (with conservative-but fast driving and a 5 tire rotation) until 75,000 and I purchased the Michelins. I know numerous friends and one family member who work for Michelin and they attested to their company's quality, etc. so I paid (top dollar) for what I thought was the better quality. I was hoping for 100,000 miles and have been VERY happy to finally be replacing them at 150,000!! Granted tread wear is now boarder line ticket-able so they're getting replaced. Durability and road noise/quietness is what I look for the most. As I shop for new ones, I'm not leaving the Michelin product line.
