Tire And Wheel Balance
- Dual-taper collet type (1)
- High-taper cone type (2)
- Possible obstruction (3)
- May not seat properly (4)
- No obstruction (5)
- Properly seated (6)
For dynamic balancing (recommended ), the balance equipment is designed to indicate the location and amount of weight to be applied to both the inner and outer rim flanges (2).
For static balancing (not recommended ), find the location of the heavy spot causing the imbalance (1). Counter balance the wheel directly opposite the heavy spot. Determine weight required to counterbalance the area of imbalance. Place half of this weight on the inner rim flange and the other half on the outer rim flange (3) at the predetermined spots.
Aluminum wheels use a different type wheel weight than steel wheels. Be sure to use the correct wheel weight for the wheel type.
Always verify the balance. When using off-vehicle equipment, remount the tire and wheel assembly 180 degrees on the balancer spindle and recheck balance. Balance variation from one spot to the other should not be more than 0.125 (1/8) ounce. If variation is more than 0.125 ounce, balancing equipment could be malfunctioning, or the wrong collet/cone may have been used.
If difficult to balance, break down the tire and wheel assembly and check for loose debris inside the tire. Prior to disassembly, mark (index) the tire at the valve stem. Use this mark in order to remount the tire in its original orientation with respect to the wheel.
