What is the definition of a traction tire?

An approved traction tire, whether on a four-wheel/all-wheel drive vehicle or a standard vehicle, must have at least an eighth of an inch of tread and be labeled M&S, All Season, or have a Mountain/Snowflake symbol. These tires can be used year round. When you install approved chains, any tire becomes a traction tire. For more information on your specific vehicle and its traction tire options, contact your local tire dealer.  more
