Studded tires allowed in WA starting Friday, Nov. 1: WSDOT

Studded snow tires will be allowed in Washington state starting Friday, Nov. 1, according to the Washington State Department of Transportation (WSDOT).

WSDOT is encouraging drivers to visit their local tire dealer to learn about stud-free winter traction tires that can be used all year round. Officials estimate that studded tires cause over $20 million worth of road damage every year.

When can I put studded snow tires on in WA?

WSDOT announced that studded tires are legal between November 1 and March 31. Drivers using studded tires outside this time frame will be fined by law enforcement.

Do I need chains if I have studded snow tires in WA?

According to WSDOT, studded tires do not satisfy the state chain requirements. This means that if you have studded snow tires and chains are required on state mountain passes, you still need to have chains.

Do I need chains if I have a 4-wheel drive, all-wheel drive vehicle?

According to WSDOT, during times when 'chains required' notices are issued, four-wheel drive (4WD) and all-wheel drive (AWD) vehicles under 10,000 pounds are not required to install chains. However, all drivers must carry chains with them in case weather conditions worsen and chain requirements are upgraded to 'chains required on all vehicles'.
