ROAD WHEEL
InspectionINFOID:0000000009464520
ALUMINUM WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel
runout.
3. Remove tire from aluminum wheel and mount wheel on a tire balance machine.
CAUTION:
DO NOT use center hole cone-type clamping machines to
hold the wheel assembly during tire removal/installation or
balancing. Damage to the wheel finish, cladding or chrome
may occur. Use only rim-type or universal lug-type clamp-
ing machines to hold the wheel assembly.
a. Set dial indicator as shown.
b. Check runout, if lateral runout (A) or radial runout (B) exceeds
the limit, install a new wheel.
STEEL WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel
runout.
a. Remove tire from steel wheel and mount on a balancer machine.
b. Set two dial indicators as shown.
c. Set each dial indicator to “0”.
d. Rotate wheel and check dial indicators at several points around the circumference of the wheel.
e. Calculate runout at each point as shown below.
f. Select maximum positive runout value and the maximum nega- tive value.
Add the two values to determine total runout.
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel.
