Tire inspection
Check on a daily basis that the tires are
free from serious damage, nails, and
stones. At the same time, check the tires
for abnormal wear.
Contact your SUBARU dealer immediate-
ly if you find any problem.
NOTE y When the wheels and tires strike curbs or are subjected to harsh treat-
ment as when the vehicle is driven on a
rough surface, they can suffer damage
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 oth-
er rough surfaces. If doing so is un-
avoidable, keep the vehicle’s speed
down to a walking pace or less, and ap-
proach the curbs as squarely as possi-
ble. Also, make sure the tires are not
pressed against the curb when you
park the vehicle. y
If you feel unusual vibration while
driving or find it difficult to steer the ve-
hicle 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 wear
Maintaining 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) at least once a month (for example,
during a fuel stop) and before any long
journey. Check 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 vehi- cle.
When a tire becomes warm, the air inside
it expands, causing the tire pressure to in-
crease. Be careful not to mistakenly re-
lease air from a warm tire to reduce its
pressure.
If this light still comes on while driv-
ing after adjusting the tire pressure,
a tire may have significant damage
and a fast leak that causes the tire to
lose air rapidly. If you have a flat tire,
replace it with a spare tire as soon
as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will flash. This in-
dicates the TPMS is unable to moni-
tor all four road wheels. Contact
your SUBARU dealer as soon as
possible for tire and sensor replace-
ment and/or system resetting. If the
light flashes, promptly contact a
SUBARU dealer to have the system
inspected.

11 - 2 6 Maintenance and service
NOTE yThe air pressure in a tire increases
by approximately 4.3 psi (30 kPa, 0.3
kgf/cm 2
) when the tire becomes warm.
y 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).
Incorrect tire pressures detract from con-
trollability and ride comfort, and they
cause the tires to wear abnormally. y
Correct tire pressure (tread worn
evenly)
Roadholding is good, and steering is re-
sponsive. Rolling resistance is low, so fuel
consumption is also lower. y
Abnormally low tire pressure (tread
worn at shoulders)
Rolling resistance is high, so fuel con-
sumption is also higher.
Do not let air out of warm tires to ad-
just pressure. Doing so will result in
low tire pressure.

y
Abnormally high tire pressure (tread
worn in center)
Ride comfort is poor. Also, the tire magni-
fies the effects of road-surface bumps and
dips, possibly resulting in vehicle damage.
„ 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 caus-
es 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 cor-
rectly balanced, have them checked and
adjusted by your SUBARU dealer. Also
have them adjusted after tire repairs and
after tire rotation.
NOTE
Loss of correct wheel alignment* caus-
es the tires to wear on one side and re-
duces the vehicle’s running stability.
Contact your SUBARU dealer if you no-
tice 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 perfor-
mance. „
Wear indicators
1) New tread
2) Worn tread
3) Tread wear indicator
Each tire incorporates a tread wear indica-
tor, which becomes visible when the depth
of the tread grooves decreases to 0.071 in
(1.8 mm). A tire must be replaced when
the tread wear indicator appears as a solid
band across the tread.
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 vehi-
cle control could lead to an acci-
dent.

11 - 2 8 Maintenance and service
NOTE
For safety, inspect the tire tread regu-
larly and replace the tires before their
tread wear indicators become visible. „Tire rotation Tire wear varies from wheel to wheel. To
maximize the life of each tire and ensure
that the tires wear uniformly, it is best to
rotate the tires every 7,500 miles (12,500
km). Rotating the tires involves switching
the front and rear tires on the right-hand
side of the vehicle and similarly switching
the front and rear tires on the left-hand
side of the vehicle. (Each tire must be kept
on its original side of the vehicle.)
Replace any damaged or unevenly worn
tire at the time of rotation. After tire rota-
tion, adjust the tire pressures and make
sure the wheel nuts are correctly tight-
ened.
After driving approximately 600 miles
(1,000 km), check the wheel nuts again
and retighten any nut that has become
loose. „
Tire replacement
The wheels and tires are important and in-
tegral parts of your vehicle’s design; they
cannot be changed arbitrarily. The tires fit-
ted as standard equipment are optimally
matched to the characteristics of the vehi-
cle and were selected to give the best pos-
sible combination of running performance,
ride comfort, and service life. It is essential
for every tire to have a size and construc-
tion 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 groundclearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern), con-
struction, and size. You are advised to re-
place the tires with new ones that are
identical to those fitted as standard equip-
ment.
For safe vehicle operation, SUBARU rec-
ommends replacing all four tires at the same time.
When a tire’s tread wear indicator
becomes visible, the tire is worn be-
yond the acceptable limit and must
be replaced immediately. With a tire
in this condition, driving at high
speeds in wet weather can cause
the vehicle to hydroplane. The re-
sulting loss of vehicle control can
lead to an accident.

Tire Identification Number (TIN)
Tire Identification Number (TIN) is
marked on the intended outboard
sidewall. The TIN is composed of four
groups. Here is a brief review of the
TIN with a breakdown of its individual
elements. (1) Manufacturer’s Identification
Mark
(2) Tire Size
(3) Tire Type Code
(4) Date of Manufacture
The first two figures identify the week,
starting with “01” to represent the first
full week of the calendar year; the
second two figures represent the
year. For example, 0101 means the
1st week of 2001. T
Other markings
The following makings are also
placed on the sidewall. V Maximum permissible inflation
pressure
The maximum cold inflation pressure
to which this tire may be inflated. For
example, “300 kpa (44 PSI) MAX. PRESS” V Maximum load rating
The load rating at the maximum per-
missible weight load for this tire. For
example, “MAX. LOAD 730 kg (1609
LBS) @ 300 kpa (44 PSI) MAX.PRESS.”
Load indices apply only to the
tire, not to the vehicle. Putting a
load rated tire on any vehicle
does not mean the vehicle can
be loaded up to the tire’s ratedload.
y Speed ratings apply only to
the tire, not to the vehicle. Put-
ting a speed rated tire on any
vehicle does not mean the ve-
hicle can be operated at the
tire’s rated speed.
yThe speed rating is void if the
tires are worn out, damaged,
repaired, retreaded, or other-
wise altered from their original
condition. If tires are repaired,
retreaded, or otherwise al-
tered, they may not be suitable
for original equipment tire de-
signed loads and speeds.
