Claim Text:
1. A method, comprising: electronically establishing a transfer function relating a tire uniformity parameter to a piezoelectric output signal for a given tire; monitoring the piezoelectric output signal from two or more piezoelectric tire sensors to measure the voltage change from each piezoelectric tire sensor while it is operating in a counter-deflection zone, wherein the counter-deflection zone comprises an area of the tire that is not in contact with a ground surface; correlating the piezoelectric output signals from each one of the two or more piezoelectric tire sensors; electronically determining the actual tire uniformity parameter value by applying the measured and correlated piezoelectric output signal voltage change levels to the established transfer function; and providing the actual tire uniformity parameter value as electronic output.
