Figure 2-84. Lateral Tire Runout

See Figure 2-84. Check tire runout by turning wheel on axle, measuring tire lateral runout.

Figure 2-85. Radial Tire Runout

1. See Figure 2-85. With a tire centered and mounted on the rim, check runout by turning wheel on axle, measuring amount of radial displacement from a fixed point near the tire.

NOTE

Make sure bead is properly seated on rim. Deflate and reseat tire if necessary.

2. Maximum tire tread runout is 2.29 mm (0.090 in.). If tire tread runout exceeds 2.29 mm (0.090 in.), remove tire from rim and check rim radial runout to see if rim is at fault. See 2.25 DISC RIM RUNOUT.

3. If rim radial runout is less than 0.76 mm (0.030 in.), tire is at fault and should be replaced. If rim radial runout is more than 0.76 mm (0.030 in.), correct by replacing wheel.

NOTE

Be sure bead is properly seated on rim. Deflate and reseat tire if necessary.

2. Maximum tire lateral runout is 1.52 mm (0.060 in.). If tire tread runout exceeds 1.52 mm (0.060 in.), remove tire from rim and check wheel rim lateral runout to see if rim is at fault. See 2.25 DISC RIM RUNOUT.

3. If rim lateral runout is less than 0.76 mm (0.030 in.), tire is at fault and should be replaced. If rim lateral runout is more than 0.76 mm (0.030 in.), correct by replacing disc wheel.
