Replacement Tires
When replacement is necessary, the original equipment
type tire should be used. Refer to the Tire Placard.
Replacement tires should be of the same size, load
range and construction as those originally on the vehicle.
Use of any other size or type tire may affect ride,
handling, speedometer / odometer calibration, vehicle
ground clearance and tire or snow chain clearance to the
body and chassis.
It is recommended that new tires be installed in pairs on
the same axle. If necessary to replace only one tire, it
should be paired with the tire having the most tread, to
equalize braking traction.
WARNING!
Do not mix different types of tires on the
same vehicle such as radial, bias and bias-
belted tires except in emergencies, because
handling may be seriously affected and may
result in loss of control.

The metric term for tire inflation pressure is the kilo
pascal (kPa). Tire pressures is usually printed in both
kPa and kgf/cm
2 on the “Tire Placard”.
Metric tire gauges are available from tool suppliers.
The chart, shown in the table, converts commonly used
inflation pressures from kPa to kgf/cm
2 and psi.
Wheels DescriptionS6RW0D2401002
Wheel Maintenance
Wheel repairs that use welding, heating, or peening are
not approved. All damaged wheels should be replaced.
Replacement Wheels
Wheels must be replaced if they are bent, dented, have
excessive lateral or radial runout, air leak through welds,
have elongated bolt holes, if lug wheel bolts won’t stay
tight, or if they are heavily rusted. Wheels with greater
runout than shown in the following may cause
objectional vibrations.
Replacement wheels must be equivalent to the original
equipment wheels in load capacity, diameter, rim with
offset and mounting configuration. A wheel of improper
size or type may affect wheel and bearing life, brake
cooling, speedometer / odometer calibration, vehicle
ground clearance and tire clearance to body and
chassis.How to Measure Wheel Runout
To measure the wheel runout, it is necessary to use an
accurate dial indicator. The tire may be on or off the
wheel. The wheel should be installed to the wheel
balancer of the like for proper measurement.
Take measurements of both lateral runout “a” and radial
runout “b” at both inside and outside of the rim flange.
With the dial indicator set in place securely, turn the
wheel one full revolution slowly and record every reading
of the indicator.
When the measured runout exceeds the specification
and correction by the balancer adjustment is impossible,
replace the wheel. If the reading is affected by welding,
paint or scratch, it should be ignored.
Lateral runout limit “a”
Aluminum wheel: 0.3 mm (0.012 in.)
Steel wheel: 0.9 mm (0.035 in.)
Radial runout limit “b”
Aluminum wheel: 0.3 mm (0.012 in.)
Steel wheel: 0.7 mm (0.028 in.)
Metric Lug Nuts and Wheel Studs
All models use metric lug nuts and wheel studs.
Metric lug nuts and wheel studs size
M12 x 1.25
If a broken stud is found, see “Front Wheel Hub, Disc,
Bolt and Bearing Check in Section 2B”, “Front Wheel
Hub, Steering Knuckle and Wheel Bearing Removal and
Installation in Section 2B”, “Rear Wheel Hub Assembly
Removal and Installation in Section 2C”. kPa kgf/cm

General Description
ABS DescriptionS6RW0D4501001
The ABS (Antilock Brake System) controls the fluid
pressure applied to the wheel cylinder of each brake
from the master cylinder so that each wheel is not locked
even when hard braking is applied.
This ABS has also the following function.
While braking is applied, but before ABS control
becomes effective, braking force is distributed between
the front and rear so as to prevent the rear wheels from
being locked too early for better stability of the vehicle.
The main component parts of this ABS include the
following parts in addition to those of the conventional
brake system.
• Wheel speed sensor which senses revolution speed
of each wheel and outputs its signal.
Rear wheel speed sensor of 4WD vehicle is
integrated in rear wheel hub assembly and supplied
as rear wheel hub assembly part.
Front wheel speed sensor and rear wheel speed
sensor of 2WD model are separated from wheel hub
assembly and supplied as spare parts.
• ABS warning light which lights to inform abnormality
when system fails to operate properly.• ABS hydraulic unit / control module assembly is
incorporated ABS control module, ABS hydraulic unit
(actuator assembly), solenoid valve power supply
driver (transistor), solenoid valve driver (transistor),
pump motor driver (transistor).
– ABS control module which sends operation signal
to ABS hydraulic unit to control fluid pressure
applied to each wheel cylinder based on signal
from each wheel speed sensor so as to prevent
wheel from locking.
– ABS hydraulic unit which operates according to
signal from ABS control module to control fluid
pressure applied to wheel cylinder of each 4
wheels.
– Solenoid valve power supply driver (transistor)
which supplies power to solenoid valve in ABS
hydraulic unit.
– Solenoid valve driver (transistor) which controls
each solenoid valves in ABS hydraulic unit.
– Pump motor driver (transistor) which supplies
power to pump motor in ABS hydraulic unit.
• G sensor which detects body deceleration speed for
4WD model.
This ABS is equipped with Electronic Brake force
Distribution (EBD) system that controls a fluid pressure
of rear wheels to best condition, which is the same
function as that of proportioning valve, by the signal from
wheel sensor independently of change of load due to
load capacity and so on. And if the EBD system fails to
operate properly, the brake warning light lights to inform
abnormality.
