I got a set of the Marathon Winters last year. They do awesome on ice, but have lots of trouble with snow. They do roll pretty well on recently plowed roads and dry pavement. If you come upon some snow more than 1/2" deep they slide and float all over the place unless it's the very light, powdery stuff. I would not recommend them for areas that get much snow. They are perfect for places that get ice and an occasional dusting. I'm thinking of trying a different studded tire with actual knobs this season.
