Abstract
A method of comparing tire noise pitch sequences based on the tire noise generated by tire tread lug stiffness variations provides a secondary examination technique used to evaluate tire noise pitch sequences that have been selected by traditional evaluation techniques. The method includes the steps of defining the tire noise pitch sequence and the pitch lengths, calculating the differential between the arc length from an arbitrary fixed reference point to the end of each pitch length in the pitch sequence and the arc length of the mean pitch length of the number of pitches from that arbitrary reference point, and analyzing the differential to identify desirable and undesirable tire noise characteristics.
