A tire tread with good noise characteristics according to the invention includes at least one circumference in which a composed sequence of a plurality of design elements, are consecutively disposed in succession. Each design element having varying circumferential lengths, or pitches wherein the pitches are reduced in number, less than or equal to 3 and preferably 2, and are disposed in a random and disordered succession is present. Also disclosed is a design method which generates automatically, in a random or pseudo-random mode, one or more sequences in which the greatest part of the obtained sequences presents good sonorous properties and are selectable across the various characteristic values obtainable from the same sequences.
