Wheel Balancing - is allowing the tires and wheels to spin without causing any vibrations. This accomplished by checking for any heavy spots on the wheel-tire combination and compensating for it by placing a measured lead weight on the opposite site of the wheel from where the heavy spot is.

The symptoms of a wheel that is out of balance are:

• Vibration in the steering wheel at certain highway speeds
  
• Vibration in the seat or floorboard at certain highway speeds
  
• Scalloped or cupped wear pattern on the tires
