2 WARNING:
psi
Do not mix different types of tires on the same vehicle such
23
as radial, bias and bias-belted tires except in emergencies,
26
because handling may be seriously affected and may result
29
in loss of control.

It is recommended that new tires be installed in pairs on the same
38
axle. If necessary to replace only one tire, it should be paired with
41
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
Placard.
Metric tire gauges are available from tool suppliers.
The chart, shown left table, converts commonly used inflation pres-
sures from kPa to psi.
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 figure below may cause
objectionable vibrations.
Replacement wheels must be equivalent to the original equipment
wheels in load capacity, diameter, rim with offset and mounting con-
figuration. A wheel of improper size or type may affect wheel and
bearing life, brake cooling, speedometer/odometer calibration, ve-
hicle 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 and radial runout at both
inside and outside of the rim flange. With the dial indicator set in
2
1
place securely, turn the wheel one full revolution slowly and record
every reading of the indicator.
1. Radial runout
2. Lateral runout
