If you live in the snow belt and want the best traction in both snow and ice, I suggest that you
use a Studless Winter /Snow tire.
The Bridgestone Blizzak WS70 and the Michelin X-Ice Xi2 are two of the best Studless Winter / Snow tires we carry.
These tires are both excellent in snow, but are also excellent on ice. I tested both of them on an indoor ice rink and they both were excellent in accelerating, braking and cornering -- even better than a studded snow tire.
Take a look at our test results.
