(a) Remount the tire on the rim 180 degrees
from its original location (Fig. 6). Ensure the tire
bead is properly seated.
(b) Re-measure the total runout. Mark the tire
at the high spot and record the measurement.

If runout is still excessive, perform the following:
• If the new high spot is within 102 mm (4.0 inch)
of the first high spot on the tire, replace the tire.
• If the new high spot is within 102 mm (4.0 inch)
of the first high spot on the wheel, the wheel may be
out of specification. Refer to Wheel Runout above.
• If the new high spot is NOT within 102 mm (4.0
inch) of either high spot, draw an arrow on the tread
from new high spot toward the original (Fig. 7).
Break down the tire and remount it 90 degrees on
rim in that direction, then re-measure runout. This
will normally reduce the runout to an acceptable
amount.

(6) Once back together, road test the vehicle for at
least 5 miles, following the format described in Road
Test. If vibration persists, and all components tested
are within specification, the tires may have an exces-
sive radial force condition. Radial force variation can
only be checked as indicated below. If this equipment
is not available, consult with the tire manufacturer.
RADIAL FORCE VARIATION
Radial Force Variation can be checked using the
Hunter GSP 9700 Vibration Control System (Wheel
Balancer) or equivalent, if available. This type of
equipment helps to correct ride disturbances by
reducing the radial force variation of an assembly
through re-indexing of the tire to wheel.

Corporation may supply reference values as guide-
