The studded tire deadline has been extended one week. Drivers must now remove their studded tires by the end of the day Thursday, April 7.

The Washington State Department of Transportation (WSDOT) extended the studded tire deadline because forecasts call for possible winter driving conditions across the mountain passes and higher-elevation areas in eastern Washington. 

 “While we’ve extended the deadline, we’re asking drivers who live in lower elevations to remove their studded tires before April 7,” said Chris Christopher, WSDOT director of maintenance operations.

 Studded tires are legal in Washington from Nov. 1 – March 31, unless extended. WSDOT officials remain concerned about safety concerns and roadway damage from studded tires. Research on studded tires consistently shows that vehicles equipped with studded tires require longer stopping distance in conditions faced by most drivers, such as wet or dry pavement.

 No one can guarantee ice- and snow-free roadways, so motorists must always be cautious when driving in wet and cold weather. Remember the key elements to safe winter driving – ice and snow, take it slow.

 Crews will continue clearing the passes, however, those traveling into the higher elevations should always prepare for winter driving conditions. This means having information on weather and roadway conditions, traction tires, and chains.

 Drivers are advised to work with local tire dealers to determine the best tires for their car and driving conditions, including traction tires legal and safe for year-round use.

 Drivers who don’t follow Washington’s rules of the road risk a visit from law enforcement.
