I just bought a set of Dunlop Graspec II for my daughters car. She goes to school in Blacksburg, Va which is in the mountains and gets consdierable snow. I bought them from the tirerack.com. absolutely awesome. I ordered them Monday afternoon, and they were at my house on Wednesday. Perfect, mounted, balanced and delivered, cheap!
They also have an excellent review section on which can be filtered. Great reviews from real poeple with the same car as you. Dependeding on where you live, different tires may be better for different situations. Study the reviews, determine you needs and decide. They have great tire and wheel packages for snows.
