Patent ID: 7584659

Claim:
A wheel balancing system comprising a wheel imbalance measuring system, a memory system, a user interface, and a processing system configured to: cause initial imbalance information relating to an initial imbalance of a wheel assembly that was measured by the wheel imbalance measuring system to be stored in the memory system; and if and only if a check spin is being performed: recall the initial imbalance information from the memory system after a residual imbalance measurement of the wheel assembly by the wheel imbalance measuring system subsequent to the initial imbalance measurement; and cause the user interface to communicate weight information to the user about an amount and placement location of at least one weight needed to correct for the initial imbalance based on the initial imbalance information recalled from the memory system after the residual imbalance measurement of the wheel assembly by the wheel imbalance measuring system subsequent to the initial imbalance measurement.
