When I got the Michelin Harmony tires in 2003, I was replacing some Goodyears that I thought were OK. The wonderful change in quality was amazing. Man, were the Michelins quiet and quick. I've just turned 94,000 miles on them (two were replaced shortly after I got them when I ran over somebody's bumper after they had a wreck). They have stayed perfectly in balance. I live in the mountains of Colorado and worked as a surgeon so my tires had to grip in winter conditions without fail. Scoobie Doo the Subaru has never been stuck or failed to get me home to 8,000 feet although we did slide a couple of times slowing and turning on glare ice. I'm ordering another set today. They may last longer than I do!
