Drivers in Oregon are reminded to remove studded tires by Friday, March 31.
Studded tires are allowed in Oregon from Nov. 1 through March 31. While the law allows the Oregon Department of Transportation to extend the studded tire season when necessary, current weather forecasts do not support an extension this year. The deadline will be the same in Washington.
ODOT encourages drivers to consider other types of traction tires or chains to help minimize roadway damage caused by studded tires. A 2014 study concluded studded tires cause about $8.5 million in damage each year to state highways.
Other types of traction tires are available. These traction tires meet the Rubber Manufacturers Association standards for use in severe snow conditions and carry an emblem on the tire sidewall of a three-peaked mountain with a snowflake in the center. Research shows these tires cause no more damage than standard all-weather radial tires and that they provide better traction than studded tires when used on bare pavement.
Drivers with studded tires on their vehicles after the deadline can be charged by law enforcement with a Class C traffic violation.
