The easy answer to this question is: winter tires! All specialized snow tires have traction on ice and snow that exceeds the best all-season tires.
How do you know which winter tire to choose? Typically, the Bridgestone Blizzaks have been class leaders in ice and snow traction. Since their introduction in 1993, we haven't found an all-season tire that can match the Blizzak's confidence-inspiring combination of deep snow, packed snow and ice traction.
Blizzak tires feature dual tread compounds consisting of outer tread cap and underlying base compounds. These tires wick away the thin layer of water that often develops on the top of packed snow and icy roads, allowing biting edges to better adhere to the surface for more traction.
However, competitors are offering even tougher competitors to the Blizzak line. For example, Michelin's X-Ice Xi3 gave a strong challenge to the Blizzak WS70 last year. It offers a good blend of traction and road manners. It also meets Michelin's Green X standard for low rolling resistance by reducing vehicle fuel consumption and emissions from CO2 gases.
When considering winter tire options this year, be sure to take a look at the new Blizzak WS80. We had a chance to take part in an introductory test pitting it against its rival from Michelin. For a complete recap of the test, read "Bridgestone Blizzak WS80 Introductory Test Report."
When purchasing winter tires, also be sure to consider a dedicated set of wheels.
