a)
Vehicle must be unladen*, parked on a level surface, and tires
checked for proper inflation and wear (tread wear indicator
must not be showing).
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
b)
Bounce vehicle up and down several times before measuring.
Standard height: Refer to SDS, SU-16.

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.
Radial runout = (A + B)/2
Lateral runout = (C + D)/2
f.
Select maximum positive runout value and the maximum
negative 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.
Wheel runout:
Refer to SDS, SU-16.
3.
