WHEEL AND TIRE SYSTEM
Tire
2. Tire
A: INSPECTION
1) Take stones, glass, nails etc. out of the tread
groove.
2) Replace the tire if as follows.
CAUTION:
When replacing a tire, make sure to use only
the same size, construction and load range as
originally installed.
(1) When large crack on side wall, damage or
crack on 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 (5,000 km/3,100 miles) as
shown in the figure, in order to prevent them from
uneven wear and to prolong their life.
• Without instruction for the direction of tire rota-
tion.
• With instruction for the direction of tire rotation.

WHEEL AND TIRE SYSTEM
Steel Wheel
3. Steel Wheel
A: REMOVAL
1) Apply the parking brake, and position the select
lever to “P” or “LOW”.
2) Set the shop jacks or a lift to specified point, and
support the vehicle with its wheels slightly contact-
ing the floor.
3) Loosen the wheel nuts.
4) Raise the vehicle until its wheels take off the
ground using a jack or a lift.
5) Remove the wheel nuts and wheels.
NOTE:
• When removing the wheels, prevent hub bolts
from damage.
• Place the wheels with their outer sides facing up-
ward to prevent wheels from damage.
B: INSTALLATION
1) Remove dirt from the mating surface of wheel
and brake rotor.
2) Attach the wheel to the hub by aligning the wheel
bolt hole with the hub bolt.
3) Temporarily attach the wheel nuts to the hub
bolts. (In the case of aluminum wheel, use SUBA-
RU genuine wheel nut for aluminum wheel.)
4) Manually tighten the nuts 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:
90 N
⋅
m (9.1 kgf-m, 65.7 ft-lb)
CAUTION:
• Tighten the wheel nuts in two or three steps
by gradually increasing the torque and working
diagonally, until they reach the specified
torque.
• Do not depress the wrench with foot. Always
use both hands when tightening.
• 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 running 1,000 km (600
miles).
C: INSPECTION
1) Deformation or damage on the rim may cause
air leakage. Check the rim flange for deformation,
crack 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 specification, remove
the tire from wheel and check runout while attach-
ing the dial gauge to positions shown in the figure.
5) If the measured runout still exceeds specifica-
tion, replace the wheel.

D: CAUTION
Aluminum wheels are easily scratched. To main-
tain their appearance and safety, do the followings:
1) Do not damage the aluminum wheels during re-
moval, installation, wheel balancing, etc. After re-
moving the 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.
