ODOT: Traction tires: you have options

When you consider your traction tire needs for winter travel, you have several alternatives. Because studded tires damage pavement, ODOT encourages drivers to consider using chains or non-studded traction tires.

“Traction tires” are studded tires, retractable studded tires, or other tires that meet the tire industry definition as suitable for use in severe snow conditions. Tires that meet Rubber Manufacturers Association standards for use in severe snow conditions carry a special symbol on the tire sidewall: a three-peaked mountain and snowflake. Research shows these tires provide better traction than studded tires on bare pavement.

Studded tire facts

• You can use studded tires in Oregon from Nov. 1 through March 31. Driving with studded tires before Nov. 1 or after March 31 is a Class C violation and carries a presumptive fine of nearly $200.
• Research shows that studded tires are more effective than all-weather tires on icy roads but are less effective in most other conditions because they may reduce traction between the road and the tire.
• Studies conducted by ODOT and others show that studded tires damage roads. Our most recent study concluded that studded tires cost Oregon more than $8.5 million per year because roadways required repaving earlier than they normally would be.
• When it rains, water collects in the pavement ruts caused by studded tires and creates dangerous driving conditions. In cold weather, that water can freeze and cause extra-slippery roads.

Alternatives to studded tires

Chains and chain-like devices

• Chains are more effective than studded tires and are becoming easier to install and use.
• Check your vehicle’s owner manual: link chains may not be recommended for use on some types of vehicles.

Other traction tires

• Traction tires provide increased traction in winter conditions over regular all-weather tires.
• They work about as well as studded tires on ice but work better than studded tires or regular tires in most other winter conditions.
• Traction tires cause no more damage to road surfaces than regular tires.

Fabric alternatives to chains

• For vehicles that cannot be fitted with tire chains, a potential option is one of the fabric cover products — sometimes called “snow socks” — that slip over your tires. These are an option if you need temporary traction to get out of a snowy spot. They are only intended for short stretches of road in adverse conditions.
