Replaced the oem Michelins at 44,000 miles. I put on the Continental Extreme ContactDWS tires which were good, but only lasted 35,000 miles and were rotated every 7,000 miles and became loud after 30,000 miles. I now have the Pirelli's and they are far superior to the Continentals and Michelins. We had a bad winter with a lot of snow and some ice, best tire I have ever had for an all season tire, I am thrilled. I expect them to last better than the Continentals. These tires are very quiet so far and handling is fine, these are not for racers, but these are the best commuter tires I have owned. I have had 90 cars in my lifetime, and these tires truly impress me. I have not seen any fuel economy benefit relative to the other tires I have had on this car, but the car now has some miles and age to it. Strongly recommend these tires.
