Oregon Department of Transportation has extended the studded tire season through Monday, April 4, as weather forecasts call for winter driving conditions in some snow zones over the coming weekend.

Motorists must have studded tires removed from their vehicles by 12:01 a.m. Tuesday April 5.

Typically, studded tires must be removed by April 1. Transportation department officials encourage drivers to not wait until the deadline if they aren't driving in snowy conditions.

Studded tires cause at least $40 million damage each year on city streets, county roads and state highways, while only about $11 million is spent each year repairing studded tire damage, ODOT reported.

Other types of traction tires meet Rubber Manufacturers Association standards for use in severe snow conditions and carry a special symbol on the tire sidewall showing a three-peaked mountain and snowflake, ODOT said in its news release. Research shows these tires provide better traction than studded tires when used on bare pavement.

Drivers with studded tires on their vehicles in Oregon after the deadline can be charged with a Class C traffic violation, which currently carries a minimum $190 fine.
