marked permanently on the inside of the rim in the
tire well. This permanent mark may be a paint dot
or line, a permanent label or a stamped impression
such as an X. An optional location mark is a small
spherical indentation on the vertical face of the out-
board flange on some non styled base steel wheels.
The tire must be removed to locate the permanent
mark on the inside of the wheel.
Before dismounting a tire from its wheel, a refer-
ence mark should be placed on the tire at the valve
stem location. This reference will ensure that it is
remounted in the original position on the wheel.
(1) Remove the tire and wheel assembly from the
vehicle and mount on a service dynamic balance
machine.
(2) Measure the total runout on the center of the
tire tread rib with a dial indicator. Record the indi-
cator reading. Mark the tire to indicate the high spot.
Place a mark on the tire at the valve stem location
(Fig. 4).

(3) Break down the tire and remount it 180
degrees on the rim (Fig. 5).

(4) Measure the total indicator runout again. Mark
the tire to indicate the high spot.
(5) If runout is still excessive, the following proce-
dures must be done.
• If the high spot is within 101.6 mm (4.0 in.) of
the first spot and is still excessive, replace the tire.
• If the high spot is within 101.6 mm (4.0 in.) of
the first spot on the wheel, the wheel may be out of
specifications. Refer to Wheel and Tire Runout.
• If the high spot is NOT within 101.6 mm (4.0
in.) of either high spot, draw an arrow on the tread
from second high spot to first. Break down the tire
and remount it 90 degrees on rim in that direction
(Fig. 6). This procedure will normally reduce the
runout to an acceptable amount, if not replace the
rim.
