11-42 Maintenance and service
. Abnormally high tire pressure (tread
worn in center)
Ride comfort is poor. Also, the tire
magnifies t he effe cts of road surfa ce
bumps and dips, possibly resulting i n
vehicle damage.
If the tire placard shows tire pressures for
the vehicle when fully loaded and for the
vehicle when towing a trailer, adjust the
tire pressures to the values that match
current loading conditions.
WARNING
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and destruction of
the tires. The resulting loss of
vehicle control could lead to an
accident.
& Wheel balance
S11AV05
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 sys-
tem problems and abnormal tire wear. If
you suspect that the wheels are not
correctly balanced, we recommend that
you 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. We recommend that you
contact your SUBARU dealer if you
notice abnormal tire wear.
NOTE
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
S11AV06
1) New tread
2) Worn tread
3) Tread wear indicator
Each tir e incorpora tes a tread wear
indicat or, which becomes visible when
the depth of the tread grooves decreases
to 1.6 mm (0.063 in). A tire must be
replaced when the tread wear indicator
appears as a solid band across the tread.
