The metric term for tire inflation pressure is the kilopascal (kPa).
Tire pressures will usually be printed in both kPa and psi on the Tire
Placard. Metric tire gauges are available from tool suppliers. The
chart, left table, converts commonly used inflation pressures 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 vehicle handling may be seriously af-
fected and may result in loss of control.
WHEELS REPLACEMENT
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 left figure may cause ob-
jectionable vibrations.
Wheels for replacement must be equivalent to the originally
equipped wheels in load capacity, diameter, rim width, off-set and
mounting configuration. A wheel of improper size or type may af-
fect wheel and bearing life, brake cooling, speedometer / odometer
calibration, ground clearance to the body and chassis.
To measure the wheel runout, it is necessary to use 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 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.
Lateral runout limit “a” : 0.90 mm (0.035 in.)
Radial runout limit “b” : 0.70 mm (0.028 in.)
METRIC LUG NUTS AND WHEEL STUDS
All models use metric lug nuts and wheel studs (size M12 x 1.25).
