Abstract: A method for balancing a wheel and tire assembly includes providing a wheel and tire assembly characterized by a rotational imbalance, and applying a fluid to the wheel and tire assembly thereby to correct the rotational imbalance. The use of a liquid to correct a rotational imbalance facilitates the automation of a balancing operation. Accordingly, another method is provided that includes determining a quantity of mass to be applied to a wheel and tire assembly to correct a rotational imbalance, and commanding an apparatus to dispense an amount of a fluid having the quantity of mass to be dispensed from a nozzle. A corresponding apparatus is also provided.
