Just swung by Discount Tire over the lunch hour and talked with a guy there about a dedicated set of winters for my X. I told him I was leaning toward the Blizzak DM-V1 (only because of the tirerack survey) and he said that he thought that was a great tire. I asked what he would run and he pointed me toward the Discoverer M+S. Since I can't really find any legit reviews for this particular tire (similar to tirerack) I'm wondering if any of you run the Discoverer as a winter tire?
