3F-2 WHEELS AND TIRES

1 psi = 6.895 kPa

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

= 98.066 kPa

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-

jectional 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 affect

wheel and bearing life, brake cooling, speedometer/odometer cal-

ibration, 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

Lateral runout limit "a": 1.20 mm (0.047 in.)

Radial runout limit "b": 1.20 mm (0.047 in.)

METRIC LUG NUTS AND WHEEL STUDS

All models use metric lug nuts and wheel studs (size M12 x 1.25).
