Tire and Wheel Runout
WARNING: This page is about a different car, the 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
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 vehicles has been driven far enough to warm the tires. For additional information, refer to NOISE, VIBRATION & HARSHNESS .
