Tire waddle is a side to side movement at the front of the vehicle and/or the rear of the vehicle. Tire waddle can be caused by the following conditions: 
|     •  | A steel belt not being straight within the tire  | 
 
|     •  | Excessive lateral runout of the tire | 
 
|     •  | Excessive lateral runout of the wheel | 
 
The tire waddle is most noticeable at a low speed of about 8-48 km/h (5-30 mph). Tire waddle may appear as ride roughness at 80-113 km/h (50-70 mph). Tire waddle may appear as a vibration at 80-113 km/h
 (50-70 mph).
