TEST DESCRIPTION
Excessive radial and lateral runout of a wheel and tire assembly can cause roughness, vibration, wheel tramp, tire wear, and steering wheel tremor.
Before checking runout and to avoid false readings caused by temporary flat spots in the tires, check runout only after the vehicle has been driven far
enough to warm tires.
The extent of the runout is measured with Radial Runout Gauge. All measurements are made on the vehicle with the tires inflated to recommended
inflation pressures and with the front wheel bearings adjusted to specifications.
TIRE RUNOUT
Measure radial and lateral tire runout at the positions shown. Runout should not exceed specifications.
WHEEL RUNOUT
Measure radial and lateral wheel runout at the positions shown. Runout should not exceed specifications.
Road Test
Verify the customer concern by performing a road test on a smooth road.
To maximize tire performance, inspect for signs of improper inflation and uneven wear, which may indicate a need for balancing, rotation, or front
suspension alignment.
