Honestly very surprised how good these tires are. Drove them through 12" of fresh snow and on many miles of Eastern Sierra dirt roads including rocks and sand. (ie: White Mountain Road and Buttermilk Road to their ends). Surprisingly grippy on hard packed and loose snow for not having a winter cert. Mileage holding up as expected and will put new ones on around 40k. I've never gotten the advertised max miles out of any tire (I work in the mountains and drive passes almost every day) and these are as good as the best. MPG is same as street tires and much better than Toyo at3. Getting 40.5MPG full year average.
