1. Before inspecting runout, and to avoid false readings caused by temporary flat spots in the tires, inspect runout only after the vehicle has been driven far enough to warm the tires.
2. Excessive radial and lateral runout of a wheel and tire assembly can cause roughness, vibration, wheel tramp, tire wear, and steering wheel tremor.
3. The extent of the runout is measured with a radial runout gauge. All measurements are made on the vehicle with the tires inflated to recommended inflation pressures.
1. Measure radial and lateral runout at the positions shown in the figure. Runout should not exceed specifications.
1. Measure radial and lateral wheel runout at the position shown in the figure. Runout should not exceed specifications. Note that the tire has been removed.
