increase in temperature could cause tread
separation, and destruction of the tires. The
resulting loss of vehicle control could lead to
an accident.
J Wheel balance
Each wheel was correctly balanced when your ve-
hicle was new, but the wheels will become unbal-
anced 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 systems problems and ab-
normal tire wear. If you suspect that the wheels are
not correctly balanced, have them checked and ad-
justed by your SUBARU dealer. Also have them ad-
justed after tire repairs and after tire rotation.
NOTE
Loss of correct wheel alignment* causes the
tires to wear on one side and reduces the ve-
hicle’s running stability. Contact your SUBARU
dealer if you notice abnormal tire wear.
* : 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.
J Wear indicators
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.
