To qualify as traction tires, your tires must have at least an eighth of an inch of tread and be labeled Mud and Snow, M+S, All Season, or have a Mountain/Snowflake symbol. Because different types of winter tires perform best under different road conditions, your local tire dealer can help you select the best option. Remember, tire dealers are busiest before and during winter storms.
Vehicles over 10,000 gross vehicle weight rating (GVWR), including some larger passenger trucks, SUVs, RVs and vehicles towing trailers, must carry chains Nov. 1 through March 31 on certain state-owned roads.

Stud Alternative - Approved This stud-less tire has over 3,200 sipes to help grip the winter roadway. The soft rubber compound helps in wet weather conditions, but is too soft for warmer, summer driving. |
 |
|
Studded - Approved
This studded tire has staggered studs designed to wear with the tire. While providing additional traction on snow and ice, studs wear down the roadway. |
 |
|
All Season - Approved
This all season tire is designed for everyday use. The rubber compound is suitable for all weather conditions. Siping (small slots cut or molded into a tire tread surface) would greatly increase this tire's traction on winter roadways. |

|
Performance - Not Approved This performance tire is the most nimble tire and has the best response on dry pavement. It has the least amount of traction on winter roadways, making it strictly a summer tire. |
