Maintenance and service/Tires and wheels
& Wheel balance
Each wheel was correctly balanced when
your vehicle was new, but the wheels will
become unbalanced as the tires become
worn during use. Wheel imbalance causes
the steering wheel to vibrate slightly at
certain vehicle speeds and detracts from
the vehicle’s straight-line stability. It can
also cause steering and suspension system problems and abnormal tire wear. If
you suspect that the wheels are not
correctly balanced, have them checked
and adjusted by your SUBARU dealer.
Also have them adjusted after tire repairs
and after tire rotation.
CAUTION
Loss of correct wheel alignment
causes the tires to wear on one side
and reduces the vehicle’s running
stability. Contact your SUBARU
dealer if you notice abnormal tire
wear.
& Wear indicators
The suspension system is designed to
hold each wheel at a certain alignment
(relative to the other wheels and to the
road) for optimum straight-line stability
and cornering performance.
cause the vehicle to hydroplane.
The resulting loss of vehicle control
can lead to an accident.
NOTE
For safety, inspect the tire tread regularly and replace the tires before their
tread wear indicators become visible.

Tread wear indicator
Each tire incorporates a tread wear
indicator, which becomes visible when
the depth of the tread grooves decreases
to 0.063 in (1.6 mm). A tire must be
replaced when the tread wear indicator
appears as a solid band across the tread.
WARNING
NOTE

When a tire’s tread wear indicator
becomes visible, the tire is worn
beyond the acceptable limit and
must be replaced immediately. With

Example of tire rotation direction mark
1) Front
If the tire has a rotation direction specification, the tire rotation direction mark is
placed on its sidewall.
When you install a tire that has the tire
rotation direction mark, install the tire with
