Tire Tread Lateral Runout

Figure 2-26. Checking Tire Lateral Runout

CHECKING TIRE ROUNDNESS (RADIAL RUNOUT)

1. Check runout by turning wheel on axle, measuring tread runout (see Figure 2-27).

2. Tire tread runout should be no more than 3/32". If tire tread runout is more 3/32", remove tire from rim and check rim bead runout to see if rim is at fault (see "Truing Wheel").

Figure 2-27. Checking Tire Radial Runout

3. If rim bead runout is less than 1 /32", tire is at fault and should be replaced. If rim bead runout is more than 1 /32" correct by tightening selected spoke nipples as outlined previously then reinstall tire and recheck tire tread runout.
