摘要： A pneumatic tire has a tread extending along the circumferential length of the tire. The tread is divided into at least two different regions across the width of the tread, and has a plurality of tread elements. Each tread element has a pitch length as measured along the circumferential length of the tire. In each of the tread regions, different pitching methods are employed. Preferably, the different pitch methods are selected and the pitch lengths in each region are arranged so that the noise frequency contribution generated in each tread regions cancels or eliminates the noise frequency contribution generated in the other tread regions.

摘要： A pneumatic tire has a tread with the radially outermost surface of the tread defining a circumferential length of the tire. The tread has a circumferentially extending groove. The circumferentially extending groove has repeating segments wherein the circumferential length of each repeating segment is at least 6.25% of the tire circumferential length. The repeating segments have an extent in the lateral direction of the tread, wherein, each directly adjacent repeating segment extends in opposite lateral directions.
