Wheel Balance Inspection and Adjustment

CAUTION:

Stones in the tread of a tire may cause injury when the wheel is spun for balancing.

Remove all stones from the tire tread before starting the balancing 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 you spin a drive wheel so that the speedometer reads higher than 55 km/h (34 mile/h), there is a risk of tire separation and differential system failure, which can cause severe personal injury and/or extensive vehicle damage. This limit must be strictly observed 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 an indicated speedometer reading of no higher than 55 km/h (34 mile/h).

NOTE:

If an on-vehicle balancing method is used for an ABS or ESP(R) equipped vehicle, with the keyless push start system ignition mode "ON", a DTC will be set for the ABS or ESP(R) system, even when there is no abnormal condition.

Do not change the keyless push start system ignition mode to "ON" while a wheel is being spun.
