摘要： A method of arranging cyclic patterns in a tire tread is disclosed, wherein design cycles in each cyclic pattern are repeated in a pitch sequence; with respect to each of the design cycles, an averaged pitch of the pitch lengths of a predetermined number of subsequent design cycles is obtained; combinations of the sequences of the averaged pitches are defined by changing phase between the sequences; with respect to the averaged pitches of the combined sequences, crossover averages are obtained; from the crossover averages in each combination, a difference between a maximum and a minimum is obtained; from the differences of the combinations, a combination having a smaller difference is found; the cyclic patterns are arranged in accordance with the phase shift of the combination having the smaller difference.
