Abstract: A tire adapted to rotate around an axis and having an outer surface defining a circumferentially extending center line that defines a center plane perpendicular to the axis. The center plane divides the tire into first and second portions. The tire includes a first series of design cycles extending circumferentially around the tire in the first portion and a second series of design cycles extending circumferentially around a tire in the second portion. The total number of design cycles in the first and second portions are equal, and the sequences of the design cycles used in the first and second portions are different in order to spread the noise generated by the tire over a broad band of frequencies.
