Winter Tire Laws in the United States

Unlike Canada and Europe, the U.S. does not have federal winter tire laws. Instead, regulations vary by state, with some requiring winter tires or chains in certain conditions.

States with Winter Tire or Chain Requirements

• Alaska: No statewide mandate, but studded tires are permitted from September 15 to April 30.
• Colorado: Chains or alternative traction devices (like snow tires) are required on certain mountain passes during winter storms.
• California: Chain controls are enforced on mountain highways (e.g., I-80, Highway 50) when signs are posted.
• Washington: Traction tires (marked M+S or 3PMSF) or chains are required on mountain passes when signs indicate.

Studded Tire Regulations

Some states allow studded tires only during specific months, while others ban them entirely. For example:

• Permitted (seasonal): Oregon, Montana, Wyoming
• Banned: Florida, Texas, Hawaii

AWD helps with acceleration but not braking. Winter tires provide better traction in all winter conditions.
