A method for balancing vehicle wheels using a single balancing weight to reduce vibrations and simplify balancing. The method involves finding the two planes on the wheel where balancing weights could be placed to cancel static and dynamic imbalance. Then, instead of using two weights, just one weight is placed on the plane that primarily cancels static imbalance. This reduces static imbalance more compared to using two weights, as it brings the center of gravity closer to the axis. The other plane's imbalance is still partially canceled by the dynamic effects of the single weight. This allows using standard balancing weights instead of customized ones, as the weight's mass is only approximate.
