Tire and Wheel Runout
WARNING: This page is about a different car, the 2004 Mazda Tribute, 2003 Mazda Tribute, and 2002 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
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 the tires.
Excessive radial and lateral runout of a wheel and tire assembly can cause roughness, vibration, wheel tramp, tire wear, and steering wheel tremor.
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.
