In Oregon, deadline to remove studded tires is March 31

PORTLAND, Ore. (AP) -- The Oregon Department of Transportation is reminding Oregonians they should remove studded tires by March 31.

Given current weather forecasts, transportation officials say they do not plan to extend the Oregon studded tire season.

The Washington State Department of Transportation announced the same deadline earlier this week.

A study completed in 2014 concluded studded tires cause about $8.5 million in damage each year on state highways. ODOT says other types of traction tires are available.
