Maintenance and service Tires and wheels Types of tires You should be familiar with type of tires present on your vehicle. The factory-fitted 17-inch tires on the WRX-STi are summer tires. The factory-fitted tires on other versions are all-season tires. The 17-inch tires that can be dealer-fitted on the WRX as an option are summer tires. All season tires All season tires are designed to provide an adequate measure of traction, handling and braking performance in year-round driving including snowy and icy road conditions. However all season tires do not offer as much traction performance as winter (snow) tires in heavy or loose snow or on icy roads. All season tires are identified by "ALL SEASON" and/ or "M+S" (Mud & Snow) on the tire sidewall.

However winter tires do not perform as well as summer tires and all season tires on roads other than snow-covered and icy roads.

Contact your SUBARU dealer immediately if you find any problem.

This type of damage does not become evident until time has passed. Try not to drive over curbs, potholes or on other rough surfaces.
