7. Steel Wheel and Tire
A: INSPECTION
1) Deformation or damage on the rim can cause
air leakage. Check the rim flange for deformation,
crack, or damage, and repair or replace as neces-
sary.
2) Take stone, glass, nail etc. off the tread groove.
3) Replace tire:
CAUTION:
IWhen replacing a tire, make sure to use only
the same size, construction and load range as
originally installed.
IAvoid mixing radial, belted bias or bias tires
on the vehicle.
(1) when large crack on side wall, damage or
crack on tread is found.
(2) when the ªtread wear indicatorº appears as
a solid band across the tread.
G4M0297
1. INSPECTION OF WHEEL RUNOUT
1) Jack-up vehicle until wheels clear the floor.
2) Slowly rotate wheel to check rim ªrunoutº using
a dial gauge.
G4M0298
Axial runout limit Radial runout limit
Steel wheel 1.5 mm (0.059 in)
Aluminum wheel 1.0 mm (0.039 in)
G4M0299
3) If rim runout exceeds specifications, remove
tire from rim and check runout while attaching dial
gauge to positions shown in figure.
4) If measured runout still exceeds specifications,
replace the wheel.

8. Aluminum Wheel
A: INSPECTION
Inspection for aluminum wheels is basically the
same as the one for steel wheels. However, check
the rim flange for cracks or damage, and replace
(not repair) aluminum wheel if air leakage is found.
B: PRECAUTIONS
Aluminum wheels are easily scratched. To main-
tain their appearance and safety, do the following:
1) Do not damage aluminum wheels during
removal, disassembly, installation, wheel
balancing, etc. After removing aluminum wheels,
place them on a rubber mat, etc.
2) While vehicle is being driven, be careful not to
ride over sharp obstacles or allow aluminum
wheels to contact the shoulder of the road.
3) When installing tire chain, be sure to install it
properly not to have a slack; otherwise it may hit
wheel while driving.
4) When washing aluminum wheel, use neutral
synthetic detergent and water. Avoid using the
cleanser including abrasive, hard brushes or an
automatic car washer.
9. Wheel Balancing
1) Proper wheel balance may be lost if the tire is
repaired or if it wears. Check the tire for dynamic
balance, and repair as necessary.
2) To check for dynamic balance, use a dynamic
balancer. Drive in the balance weight on both the
top and rear sides of the rim.
3) Some types of balancer can cause damage to
the wheel. Use an appropriate balancer when
adjusting the wheel balance.
4) Use genuine balance weights.
CAUTION:
I55 g (1.94 oz) weight used with aluminum
wheel is not available.
IBalance weights are available for use with
any of 14- to 16-inch wheels.

10. Installation of Wheel
Assembly to Vehicle
1) Attach the wheel to the hub by aligning the
wheel bolt hole with the hub bolt.
2) Temporarily attach the wheel nuts to the hub
bolts. (In the case of aluminum wheel, use
SUBARU genuine wheel nut for aluminum wheel.)
3) Manually tighten the nuts making sure the
wheel hub hole is aligned correctly to the guide
portion of hub.
4) Tighten the wheel nuts in a diagonal selection
to the specified torque. Use a wheel nut wrench.
Wheel nut tightening torque:
88
±10 N´m (9±1 kg-m, 65±7 ft-lb)
CAUTION:
ITighten the wheel nuts in two or three steps
by gradually increasing the torque and working
diagonally, until the specified torque is
reached. For drum brake models, excess tight-
ening of wheel nuts may cause wheels to ªjud-
derº.
IDo not depress the wrench with a foot;
Always use both hands when tightening.
IMake sure the bolt, nut and the nut seating
surface of the wheel are free from oils.
5) If a wheel is removed for replacement or for
repair of a puncture, retighten the wheel nuts to the
specified torque after running 1,000 km (600
miles).
11. Tire Rotation
If tires are maintained at the same positions for a
long period of time, uneven wear results.
Therefore, they should be periodically rotated.
This lengthens service life of tires.
CAUTION:
When rotating tires, replace unevenly worn or
damaged tires with new ones.
