A tire tread has a plurality of base pitches arranged in at least two circumferential sections around the tire. The base pitches have at least two different pitch lengths and include a plurality of load-supporting tread blocks. The different pitch lengths of the base pitches form a pitch sequence in each circumferential section of the tire. The pitch sequences in the sections are arranged such that the noise produced by the base pitches in the tire tread is a low level, distributed noise to reduce the noise produced by the tire when the tire is in use.
