Bridgestone Blizzak WS70
Michelin X-Ice Xi2
The Blizzaks are one of our best sellers, and the WS70 is the winter / snow tire choice for my personal car. They offer superior traction in snow and on ice. They are, however, a little soft on dry pavement. For this reason, we would also suggest the Michelin X-Ice Xi2. They have excellent winter traction as well, but behave more like your all-season tires on dry pavement. The Firestone Winterforce is a great entry-level winter / snow tire that is also studdable. And when you're looking at Firestone tire prices, the Winterforce is an excellent choice for the budget-minded consumer.
You may also want to consider snow wheels to go along with your new Chevy tires to create a Winter / Snow Tire & Wheel Package. Packages come pre-assembled and ready to bolt on. This saves you time and money and gives you the freedom to easily change between summer and winter packages.
