Tires and wheels
J Types of tires
You should be familiar with type of tires present on
your vehicle.
B All season tires
The factory-installed tires on your new vehicle are all
season tires.
All season tires are designed to provide an ade-
quate 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.
B Summer tires
The optional, dealer-installed, 17-inch tires recom-
mended for the WRX are summer tires.
Summer tires are high-speed capability tires best
suited for highway driving under dry conditions.
Summer tires are inadequate for driving on slippery
roads such as on snow-covered or icy roads.
If you drive your vehicle on snow-covered or icy
roads, we strongly recommend the use of winter
(snow) tires.
When installing winter tires, be sure to replace all
four tires.
B Winter (snow) tires
Winter tires are best suited for driving on snow-cov-
ered and icy roads. However winter tires do not per-
form as well as summer tires and all season tires on
roads other than snow-covered and icy roads.
J Tire inspection
Check on a daily basis that the tires are free from
serious damage, nails, and stones. At the same
time, check the tires for abnormal wear.
Contact your SUBARU dealer immediately if you find
any problem.
NOTE
D When the wheels and tires strike curbs or are
subjected to harsh treatment as when the vehicle
is driven on a rough surface, they can suffer
damage that cannot be seen with the naked eye.
This type of damage does not become evident
until time has passed. Try not to drive over
curbs, potholes or on other rough surfaces. If
doing so is unavoidable, keep the vehicle’s
speed down to a walking pace or less, and ap-
