2D-2 Wheels and Tires:
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 the table, converts commonly used
inflation pressures from kPa to kgf/cm
2 and psi.
Wheels Description
S4RS0A2401002
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 nuts 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”: 1.40 mm (0.055 in.)
Radial runout limit
“b”: 1.14 mm (0.045 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,
Nut and Bearing Check: in Section 2B”, “Front Wheel
Hub, Steering Knuckle and Wheel Bearing Removal and
Installation: in Section 2B”, “Rear Suspension
Component Location: in Section 2C”, “Rear Brake Drum
Removal and Installation: in Section 4C”and “Wheel
Bearing and Wheel Stud Bolt Removal and Installation:
in Section 2C” for Note and Replacement procedure.
Irregular and/or Premature Wear Description
S4RS0A2401003
Irregular and premature wear has many causes. Some
of them are: incorrect inflation pressures, lack of tire
rotation, driving habits, improper alignment.
If the following conditions are noted, rotation is
necessary:
• Front tire wear is different from rear.
• Uneven wear exists across the tread of any tire.
• Front tire wear is unequal between the right and left.
• Rear tire wear is unequal between the right and left.
• There is cupping, flat spotting, etc.
A wheel alignment check is necessary if following
conditions are noted:
• Front tire wear is unequal between the right and left.
• Wear is uneven across the tread of any front tire.
