Tire
WHEEL AND TIRE SYSTEM
2. Tire
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
ID. TER ID, OPERATION, Subaru Select Monitor.>

Aluminum Wheel
WHEEL AND TIRE SYSTEM
3. Aluminum Wheel
A: REMOVAL
1) Apply the parking brake, and position select le-
ver to “P” or “LOW”.
2) Set the shop jacks or a lift to the specified points,
and support the vehicle with its wheels slightly con-
tacting the floor.
3) Loosen the wheel nuts.
4) Raise the vehicle until its wheels are off the
ground using the jack or a lift.
5) Remove the wheel nuts and wheels.
NOTE:
•When removing the wheels, be careful not to
damage the hub bolts.
•Place the wheels with their outer sides facing up-
ward to prevent wheels from being damaged.
B: INSTALLATION
1) Remove dirt from the mating surface of the
wheel and brake rotor.
2) Attach the wheel to the hub by aligning the wheel
bolt holes with the hub bolts.
3) Temporarily attach the wheel nuts to the hub
bolts. (In the case of aluminum wheels, use SUBA-
RU genuine wheel nuts for aluminum wheels.)
4) Tighten the nuts by hand, making sure the wheel
hub hole is aligned correctly to the guide portion of
hub.
5) Tighten the wheel nuts in a diagonal selection to
the specified torque. Use a wheel nut wrench.
Wheel nut tightening torque:
110 N·m (11.2 kgf-m, 81.1 ft-lb)
CAUTION:
•Tighten the wheel nuts in two or three steps
by gradually increasing the torque on opposing
nuts, until they reach the specified torque.
•Do not push the wrench by foot. Always use
both hands when tightening the nuts.
•Make sure the bolt, nut and the nut seating
surface of the wheel are free from oil.
6) If a wheel is removed for replacement or for re-
pair of a puncture, retighten the wheel nuts to the
specified torque after driving 1,000 km (600 miles).
C: INSPECTION
1) Deformation or damage to the rim may cause air
leakage. Check the rim flange for deformation,
cracks or damage, and repair or replace as neces-
sary.
2) Jack-up the vehicle until wheels clear the floor.
3) Slowly rotate the wheel to check rim “runout” us-
ing a dial gauge.
Rim runout:
4) If the rim runout exceeds specifications, remove
the tire from wheel and check runout while attach-
ing dial gauge to positions shown in the figure.
5) If the measured runout still exceeds specifica-
tions, replace the wheel.
D: CAUTION
Aluminum wheels are easily scratched. To main-
tain their appearance and safety, be careful of the
following:
1) Do not damage the aluminum wheels during re-
moval, installation, wheel balancing, etc. After re-
moving aluminum wheels, place them on a rubber
mat etc.
2) When washing the aluminum wheel, use neutral
synthetic detergent and water. Avoid using the
cleanser including abrasive, hard brushes or an au-
tomatic car washer.

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.
