Mark the tire to indicate the high spot. Place a m a r k

on the tire at the valve stem location (Fig. 8).

(2) Break down the tire and remount it 180 de

grees on the rim (Fig. 9).

(3) Measure the total indicator runout again. Mark

the tire to indicate the high spot.

(4) 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 spec

ifications. Refer to Wheel and Tire Runout.

• If the high spot is NOT within 101.6 m m (4.0 in.)

of either high spot, draw an arrow on the tread from

second high spot to first. Break down the tire and re

mount it 90 degrees on the rim in t h a t direction (Fig.

10). This procedure will normally reduce the runout

to an acceptable amount.

TIRE AND WHEEL RUNOUT

Radial runout is the difference between the high

and low points on the tire or wheel (Fig. 11).

Lateral runout is the w o b b l e of the tire or wheel.

Radial runout of more t h a n 1.5 mm (.060 inch)

measured at the center line of the tread may cause

the vehicle to shake.
