Replaced OEM Michelins at approx. 62,000 miles. Those were OK tires, but they always seemed to be really loud. As those tires wore down I could hardly hear on my mobile phone. I had my dealer parts dept. order thru Tire Rack and charge me the same price that I would of paid for them ordering direct. Tires arrived fast and it was a painless process. I rotate every 5,000-7,000 miles and the tread life is at the point now where I have to get a new set. I drive a lot of Highway miles and have my trunk ususlly loaded heavy with sales literature and samples, but that has not diminished the wear pattern at all. These tires seem to be quieter than the OEM tires and have kept my gas mileage averaging around 30 mpg. I have never been able to get more than 33.5 mpg, but that's probably just the car itself. I would definately recommend this tire to anyone of my family and friends. My new set will be the Turanza Serenity Plus, maybe I can squeeze 90,000 miles from them and a little better gas mileage.
