Wheel Balance Inspection and Adjustment

WARNING:
Stones in the tread of a tire may injure the operator when the wheel is spun for balancing. Remove all stones from the tire tread before starting the operation. This is also important to obtain a good balancing result.

Before starting operation of wheel balance inspection and adjustment, remove all mud and other deposits from the rim inside area. Also check that tire is free of damage.
Follow recommendations of wheel balancing equipment's manufacturer.

Off-Vehicle Balancing
Electronic off-vehicle wheel balancers are easy to use. Most of them provide dynamic, two-plane balancing with high accuracy (usually capable of detecting imbalance of within 1/8 ounce), although they cannot be used for correcting brake disc imbalance unlike with on-vehicle wheel balancers.

On-Vehicle Balancing
On-vehicle balancing methods vary with equipment and tool manufacturers. Be sure to follow each manufacturer's instructions during balancing operation.

WARNING:
If a drive wheel is spun at a speed higher than 55 km/h (35 mph) in speedometer reading, there is a risk of tire disintegration and differential system failure, eventually resulting in serious personal injuries and/or extensive vehicle damage including differential failure. This limit must be respected because the speedometer indicates only one-half of the actual wheel speed when one drive wheel is spinning while the other drive wheel is stopped. Be sure to limit the spinning speed of a drive wheel to 55 km/h (35 mph) in speedometer reading.

CAUTION:
If an on-vehicle balancing method is used for an ABS or ESP equipped vehicle with the keyless push start system ignition mode "ON", a diagnostic trouble code (DTC) will be set for the ABS or ESP even when the system is in normal condition. Do not change the keyless push start system ignition mode to "ON" while a wheel is being spun.
