ABSTRACT:
A method and apparatus of characterizing for tire pressure imbalances in a set of tires of vehicle, the vehicle having four wheels, and each wheel having a sensor generating a pulse for a predetermined amount of distance traveled by the wheel including entering a first characterization mode, accumulating a number of pulses from each sensor and adding the number of pulses from each sensor to generate a first record total pulse count in the characterization mode, generating a second record total pulse count in the characterization mode, determining if the first record is similar to the second record, and discarding at least one of the first and second records if the first and second records do not meet a criteria.
