Abstract: A method for balancing a vehicle wheel includes mounting a wheel to be balanced on a rotating shaft of a machine computerized for measuring imbalances, and selecting an optimum commercial balancing weight which, when positioned on a correction plane, minimizes residual imbalance on reference planes of the wheel where the balancing tolerance is considered. One compares the residual imbalance value at the reference planes with the prescribed balancing tolerance after subtracting a vector of the static imbalance generated by the optimum balancing weight. An indicator device is activated to indicate on the wheel the optimum axial position of a correction plane for a balancing weight where the residual imbalance at the reference planes is within tolerance.

Abstract: An apparatus for balancing a vehicle wheel simultaneously shows both dynamic imbalance and static imbalance. At least one corrective weight is attached to the wheel to correct the static imbalance. A residual static imbalance is then determined after attachment of the corrective weight. Finally, the corrective weight is adjusted to reduce the residual static imbalance.
