Tire and Wheel Balance






TIRE AND WHEEL BALANCE

It is recommended that a two plane service dynamic balancer be used when a tire and wheel assembly require balancing. Refer to balancer operation instructions for proper cone mounting procedures. Typically aluminum wheels use the back cone mounting method without a cone spring.


NOTE: Static should be used only when a two plane balancer is not available.

NOTE: Aluminum wheels require coated balance weights and special alignment equipment.

Wheel balancing can be accomplished with either on or off vehicle equipment. When using on-vehicle balancing equipment, remove the opposite wheel/tire. Off-vehicle balancing is recommended.






For static balancing, find the location of the heavy spot (1) causing the imbalance. Counter balance wheel directly opposite the heavy spot. Determine weight required to counter balance the area of imbalance. Place half of this weight (3) on the inner rim flange and the other half on the outer rim flange.






For dynamic balancing, the balancing equipment is designed to locate the amount of weight (2) to be applied to both the inner and outer rim flange.
