NOTE:
All wheel fasteners are important attaching parts in that they could affect the performance of vital parts
and systems, and/or could result in major repair expense. They must be replaced with one of the same part
number or with an equivalent part if replacement becomes necessary. Do not use a replacement part of
lesser quality or substitute design. Torque values must be used as specified during reassembly to assure
proper retention of all parts.
There is to be no welding as it may result in extensive damage and weakening of the metal.

GENERAL DESCRIPTION
TIRES
This vehicle is equipped with the following tire.
145/70 SR12 or 5.65-12-4PR
The tire is of tubeless type. The tire is designed to operate satisfactorily with loads up to the full rated load capacity
when inflated to the recommended inflation pressures.
Correct tire pressures and driving habits have an important influence on tire life. Heavy cornering, excessively rapid
acceleration, and unnecessary sharp braking increase tire wear.
WHEELS
Standard equipment wheels are the following steel wheel.
12 y 4 J
REPLACEMENT TIRES
When replacement is necessary, the original equipment type tire should be used. Refer to TIRE PLACARD. Re-
placement 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 clear-
ance 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.
The metric term for tire inflation pressure is the kilopascal (kPa).
Tire pressures is usually printed in both kPa and psi on the tire plac-
ard.
Metric tire gauges are available from tool suppliers.
The chart, shown table, converts commonly used inflation pressur-
es from kPa to psi.
WARNING:
Do not mix different types of tires on the same vehicle
such as radial, bias and bias-belted tires except in emer-
gencies, because handling may be seriously affected
and may result in loss of control.

REPLACEMENT WHEELS
Wheels must be replaced if they are bent, dented, have excessive
lateral or radial runout, leak air through welds, have elongated bolt
holes, if lug nuts won’t stay tight, or if they are heavily rusted.
Wheels with greater runout than shown in figure may cause objec-
tional vibrations.
Replacement wheels must be equivalent to the original equipment
wheels in load capacity, diameter, rim width, offset and mounting
configuration. A wheel of improper size or type may affect wheel
and bearing life, brake cooling, speedometer/odometer calibra-
tion, vehicle ground clearance and tire clearance to body and chas-
sis.
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 measure-
ment.
Take measurements of both lateral runout (1) and radial runout (2)
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 correc-
tion by the balancer adjustment is impossible, replace the wheel.
If the reading is affected by welding, paint or scratch, it should be
ignored.
