Studded tires have been a thorn in the Oregon Department of Transportation’s side for many years. And it’s no surprise why. As federal funding and gas tax revenue fall off a cliff, the agency is struggling to pay its bills. Meanwhile those little spikes used by many Oregonians at the first hint of cold weather cause an estimated $50-60 million in damage each year. Now, 15 years after they first looked into the issue, ODOT has launched a new effort to learn more about how many people use studded tires and exactly how much damage they do.
