A: INSPECTION
1) Take stones, glass, nails etc. out of the tread
groove.
2) Replace tires in the following cases.
CAUTION:
•When replacing a tire, make sure to use only
tires of the same size, construction and load
range as originally installed.
•Use a tire changer when removing the tire
from the wheel.
•On models equipped with tire pressure mon-
itoring systems, do not use the bead breaker in
a 90° area centered on the transmitter to pre-
vent damaging the transmitter.
•To prevent damaging the transmitter, set the
tire changer boom in the position as shown in
the figure.
(1) If large cracks on side wall, damage or
cracks on the tread is found.
(2) When the “tread wear indicator” appears as
a solid band across the tread.
3) When a crack on tire valve is found, replace the
tire valve.
1. TIRE ROTATION
Rotate tires periodically (12,500 km/7,500 miles) as
shown in the figure, in order to prevent them from
uneven wear and to prolong their life.
NOTE:
Vehicles equipped with tire pressure monitoring
systems will require re-registration of transmitter

Wheel Balancing
WHEEL AND TIRE SYSTEM
4. Wheel Balancing
A: ADJUSTMENT
NOTE:
The balance weight for the outside of the wheel
uses an adhesive type weight. Change the setting
of the wheel balancer to an adhesive type weight.
1) Remove the balance weights.
CAUTION:
•Be careful not to damage the wheel.
•Completely remove the double–sided tape of
the adhesive type weight from the wheel.
2) Using the wheel balancer, measure wheel bal-
ance.
3) Select a weight close to the value measured by
wheel balancer.
CAUTION:
Use SUBARU genuine balance weights.
4) Install the selected weight to the point designat-
ed by the wheel balancer.
CAUTION:
•Remove grease from adhesive type weight
applying surface of wheel.
•Press the adhesive type weight by 25 N (2.5
kgf, 5.6 lb) or more per 5 g (0.18 oz) for more
then 2 seconds and attain full adhesion.
•The total weight of all adhesive weight on
models with transmitters (tire pressure sensor)
is to be 120 g (4.23 oz) or less.

“T–type” Tire
WHEEL AND TIRE SYSTEM
5. “T–type” Tire
A: NOTE
“T–type” tire for temporary use is equipped as a
spare tire.
CAUTION:
•Do not drive at a speed greater than 100 km/h
(62 MPH).
•For the model with tire pressure monitoring
system, the indicator light may blink when run-
ning with the “T-type” tire.
B: REPLACEMENT
Refer to Aluminum Wheels for removal and instal-
lation procedures of the “T–type”. REMOVAL, Aluminum Wheel.>
CAUTION:
The “T–type” tire is only for temporary use. Re-
place with a conventional tire as soon as possi-
ble.
C: INSPECTION
1) Check the tire air pressure.
Specifications:
420 kPa (4.2 kg/cm2, 60 psi)
2) Take stones, glass, nails, etc. out of the tread
groove.
3) Check the tires for deformation, cracks, partial
wear, or wear.
CAUTION:
Replace the tire with a new one if defective.
