WARNING
Driving at high speeds with excessively low tire pressures can cause the tires to deform
severely and to rapidly become hot. A sharp
increase in temperature could cause tread
separation, and destruction of the tires. The resulting loss of vehicle control could lead toan accident.
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 fromthe vehicle ’s straight-line stability. It can also cause
steering and suspension system 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.
Wear indicators
A) New tread
B) Worn tread
1) 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
