Checking Tire Lateral Runout
1. See Figure 2-23. Turn wheel on axle and measure
amount of displacement from a fixed point to tire side-
wall.
2. Tire tread lateral runout should be no more than 0.080 in.
(2.03 mm). If runout is more than 0.080 in. (2.03 mm),
remove tire from rim.
3. Check rim bead side runout. See 2.8 CHECKING CAST
RIM RUNOUT. Replace rims not meeting specifications.
4. Install tire and check again for tire tread lateral runout.
Checking Tire Radial Runout
1. See Figure 2-24. Turn wheel on axle and measure tread
radial runout.
2. Tire tread radial runout should not be greater than 0.060
in. (1.52 mm). If runout exceeds specification, remove
tire from rim.
3. Check rim bead runout. See 2.8 CHECKING CAST RIM
RUNOUT. Replace rims not meeting specifications.
4. Install tire and check tire tread radial runout again.
ADJUSTMENT
Wheel Balancing
Wheel balancing is recommended to improve handling and
reduce vibration, especially at high road speeds.
In most cases, static balancing using WHEEL TRUING AND
BALANCING STAND (Part No. HD-99500-80) will produce
satisfactory results. However, dynamic balancing, utilizing a
wheel spinner, can be used to produce finer tolerances for
better high-speed handling characteristics. Follow the instruc-
tions supplied with the balance machine you are using.
WEIGHTS FOR CAST WHEELS
The maximum weight permissible to accomplish balance is:
● 1.0 oz. (28 g) total weight applied to the front wheel.
● 2.0 oz. (56 g) total weight applied to the rear wheel.
Wheels should be balanced to within 1/4 oz. (7 g) at 60 MPH
(97 KM/H).
See Figure 2-25. Use only WHEEL WEIGHTS (Part No.
43692-94Y) which have special self-adhesive backings.
Apply WHEEL WEIGHTS to the flat surface of the wheel rim.
1. Make sure that area of application is completely clean,
dry and free of oil and grease.
2. Remove paper backing from weight. For additional adhe-
sive strength, apply three drops of Loctite Super-Bonder
420 to adhesive side of weight.
3. Place weight on flat surface of wheel rim.
4. Press weight firmly in place and hold for ten seconds.
5. Allow eight hours for adhesive to cure completely before
using wheel.
