After 10,000 miles, I'm impressed with these tires. While not as tenacious as studdable snows, these tires dont suffer from the noise issues with which studdable snow tires are burdened. The ride comfort is a fair trade, as these tires still provide very nice light and deep snow grip, and they seem additionally competent on the ice.
This was a tough winter with lots of opportunities to drive in challenging conditions. I drove through deep snow, across hard packed snow, two inch thick ice on the freeway. My Prius tore through it all. 7 plus inches of unplowed snow posed no issue. I drove at over 60 mph on two inch thick ice (just east of Lake Michigan) and found myself laughing at how easy it was.
What's more, and this is why I find myself buying Michelin tires over and over again, the tires are remarkably quiet in the dry. Although I have a separate set of summer wheels and tires (purchased from Tire Rack) I could easily run these tires with few issues. But I won't.
For those of you who drive a Prius or other hybrid, or are simply concerned with the mileage impact, I have found these tires, which are LRR, to be very good. I can easily average over 50mpg with my Prius in the warm, on fair weather tires. With these winter tires, I found my mileage to be closer to 44. How much of the decline is attributable to the tires, and how much is attributable to the cold weather, I cannot be certain. But now that it's a bit warmer, Ive seen my mileage climb back up to 50mpg, even though the winter tires are still mounted.
I would definitely buy these again, and I would recommend them. I hope this review has been helpful.
