Match Balance (Optimization)

The Match Balance (Tire/Rim Weight Optimization)

procedure is used to determine the best mating of tire

and rim that will result in the least amount of total unbal-

ance of the assembly. It requires two spins and two

rotations of the tire on the rim. Match Balance may be

needed when:

• The customer complains of ride problems.

Note: A high unbalance may indicate the improper

mounting of the assembly on the balancer, or a rim that

is out of round or malformed, or a tire with a bubble or

other problem. If the unbalance is excessive, it may be

prudent to replace the rim, the tire, or both. If either is

replaced, do not continue with Match Balance. Balance

the new tire and rim and evaluate the readings.

Match Balance Mode

If you choose to use Match Balance to correct for a

condition, such as a large static unbalance, then follow

the information box instructions for the MATCH BAL-

ANCE procedure as outlined in the following steps.

Note: Use this procedure only after the wheel has

spun and the corrective weight amount is displayed.

Note: Use the total static display option. See BAL-

ANCE OPTIONS, page 11, for further details.

1. Press and hold the SHIFT key and press 5 to select

the Match Balance mode. A “1” will appear in the out-

board weight display.

2. Raise the hood and rotate the wheel until the valve

stem is at top-dead-center. Mark the tire sidewall at the

valve stem.

3. Press 1 on the control panel; a “2” will appear in

the outboard weight display.

4. Remove the wheel assembly from the balancer.

WARNING

The Match Balance involves the loosening of

tire beads and the inflation of a tire. Training

is necessary in tire changer operation and

understanding the dangers involved dur-

ing bead seating and tire inflation before

attempting this stage of the Match Balance

procedure. Read the operators manual sup-

plied with the tire changer and consult a

supervisor.

5. Using a tire changer, rotate the tire 180 degrees

on the rim.

6. Remount wheel assembly on the balancer. Press

2 on the control panel; a “3” will appear in the outboard

weight display.

7. Lower the hood and press START. The wheel

spins.

8. When the wheel stops spinning, raise the hood

and rotate the wheel until the valve stem is at top-dead-

center.

9. Press 4 on the control panel.

Weight amounts appear on the control panel. The

amount in the inboard weight display is the weight

imbalance for the rim. The amount in the outboard

weight display is the weight imbalance for the tire. Use

these weight amounts to determine the suitability of

the rim or tire.

Note: If either the rim or the tire weight amount is

close to zero or zero then using Match Balance will not

affect the total unbalance of the assembly.

10. Rotate the wheel until the outboard weight posi-

tion bar flashes. Mark the tire at top-dead-center.

11. Remove wheel assembly from balancer.

WARNING

The Match Balance involves the loosening of

tire beads and the inflation of a tire. Training

is necessary in tire changer operation and

understanding the dangers involved dur-

ing bead seating and tire inflation before

attempting this stage of the Match Balance

procedure. Read the operators manual sup-

plied with the tire changer and consult a

supervisor.

12. Using a tire changer, rotate the tire until the mark

is aligned with the valve stem.

13. Remount the wheel assembly on the balancer.

14 . Press NEXT or START to exit Match Balance.

Select a balancing mode and balance the wheel assem-

bly.
