    摘要： A method and system providing for tire tread design with improved noise characteristics is disclosed. The volume of air created by the lateral grooves that separate each tread block, referred to as a void, is computed at various sampling areas around a tire to generate a void function. The void function is measured at the boundaries of the tire footprint. The footprint of the tire is the portion of the tire that is in contact with the road surface. There is a correlation between the void function, and tire noise. Depending on the tread design, the void function changes as the tire rotates. By minimizing fluctuation in the void function over the course of a complete tire rotation, the tire noise can be reduced.

    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.
