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 unavoid-
able, keep the vehicle’s speed down to
a walking pace or less, and approach
the curbs as squarely as possible. Also,
make sure the tires are not pressed
against the curb when you park the
vehicle.
.If you feel unusual vibration while
driving or find it difficult to steer the
vehicle in a straight line, one of the tires
and/or wheels may be damaged. Drive
slowly to the nearest authorized
SUBARU dealer and have the vehicle
inspected.&Tire pressures and wearMaintaining the correct tire pressures
helps to maximize the tires’service lives
and is essential for good running perfor-
mance. Check and, if necessary, adjust
the pressure of each tire (including the
spare - if equipped) at least once a month
(for example, during a fuel stop) and
before any long journey.
Tire placardCheck the tire pressures when the tires are
cold. Use a pressure gauge to adjust the
tire pressures to the values shown on the
tire placard. The tire placard is located on
the door pillar on the driver’s side.
Driving even a short distance warms up
the tires and increases the tire pressures.
Also, the tire pressures are affected by the
outside temperature. It is best to check tire
pressure outdoors before driving the ve-
hicle.
When a tire becomes warm, the air inside it
expands, causing the tire pressure to
increase. Be careful not to mistakenly
release air from a warm tire to reduce its
pressure.
NOTE.The air pressure in a tire increases
by approximately 4.3 psi (30 kPa, 0.3
kgf/cm
2) when the tire becomes warm.
.The tires are considered cold when
the vehicle has been parked for at least
three hours or has been driven less
than one mile (1.6 km).
WARNING
Do not let air out of warm tires to
adjust pressure. Doing so will result
in low tire pressure.
Incorrect tire pressures detract from con-
trollability and ride comfort, and they cause
the tires to wear abnormally.

1) Correct tire pressure (tread worn evenly)
Roadholding is good, and steering is
responsive. Rolling resistance is low, so
fuel consumption is also lower.
2) Under inflated tire (tread worn on
shoulders)
Rolling resistance is high, so fuel con-
sumption is also higher.3) Over inflated (tread worn in the center)
Ride comfort is poor. Also, the tire
magnifies the effects of road-surface
bumps and dips, possibly resulting in
vehicle damage.
If the tire placard shows tire pressures for
the vehicle when fully loaded, adjust the
tire pressures to the values that match the
loading conditions.
WARNING
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly heat up. A sharp increase in
temperature could cause tread se-
paration, and destruction of the
tires. The resulting loss of vehicle
control could lead to an accident.&Wheel balanceEach 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 notcorrectly 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.NOTEThe 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 indicators1) New tread
2) Worn tread
3) Tread wear indicatorEach tire incorporates a tread wear in-
dicator, 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
When a tire’s tread wear indicator
becomes visible, the tire is worn
beyond the acceptable limit and
must be replaced immediately. With
a tire in this condition, driving at
high speeds in wet weather cancause the vehicle to hydroplane. The
resulting loss of vehicle control can
lead to an accident.
NOTEFor safety, inspect tire tread regularly
and replace the tires before their tread
wear indicators become visible.&Rotational direction of tiresExample of rotational direction marked on

Vehicles equipped with unidirectional
tires
1) FrontTire wear varies from wheel to wheel.
Move the tires to the positions shown in the
illustration each time they are rotated. For
the tire rotation schedule, refer to the
“Warranty and Maintenance Booklet”.
Replace any damaged or unevenly worn
tires at the time of rotation. After tire
rotation, adjust the tires pressures and
make sure the wheel nuts are correctly
tightened.
After driving approximately 600 miles
(1,000 km), check the wheel nuts again
and retighten any nut that has become
loose.
For handling alloy wheels, refer to“Alloywheels”F11-27.
&Tire replacementThe wheels and tires are important and
integral parts of your vehicle’s design; they
cannot be changed arbitrarily. The tires
fitted as standard equipment are optimally
matched to the characteristics of the
vehicle and were selected to give the best
possible combination of running perfor-
mance, ride comfort, and service life. It is
essential for every tire to have a size and
construction matching those shown on the
tire placard and to have a speed symbol
and load index matching those shown on
the tire placard.
Using tires of a non-specified size detracts
from controllability, ride comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incor-
rect body-to-tire clearances and inappro-
priately changes the vehicle’s ground
clearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern), con-
struction, and size. You are advised to
replace the tires with new ones that are
identical to those fitted as standard equip-
ment.
For safe vehicle operation, SUBARUrecommends replacing all four tires at the
same time.
WARNING
.When replacing or installing tire
(s), all four tires must be the same
for following items.
(a) Size
(b) Circumference
(c) Speed symbol
(d) Load index
(e) Construction
(f) Manufacturer
(g) Brand (tread pattern)
(h) Degrees of wear
For the items (a) to (d), you must
obey the specification that is
printed on the tire placard. The
tire placard is located on the
driver’s door pillar.
If all of four tires are not the same
for items (a) to (h), serious me-
chanical damage could occur to
the drive train of your car, and
affect the following.

It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
.Use only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires.
Doing so can dangerously re-
duce controllability, resulting in
an accident.
&Wheel replacementWhen replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available
from SUBARU dealers.
WARNING
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper opera-
tion and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of
vehicle control could lead to an
accident.NOTEWhen any of the wheels are removed
and replaced for tire rotation or for any
other reason, always check the tight-
ness of the wheel nuts after driving
approximately 600 miles (1,000 km). If
any nut is loose, tighten it to the
specified torque.
Alloy wheelsAlloy wheels can be scratched and da-
maged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
.When any of the wheels are removed
and replaced for tire rotation or to change a
flat tire, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose,
tighten it to the specified torque.
.Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.
.Never let the wheel rub against sharp
protrusions or curbs.
.When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for alloy wheels.
.When stacking and storing removed
tires, place shock-absorbing material be-
tween the tires to protect the wheels from
becoming scratched.
