TIRE WITH TREAD PATTERN, DESIGN METHOD FOR TIRE WITH TREAD PATTERN, AND MANUFACTURING METHOD FOR TIRE WITH TREAD PATTERN

摘要

PROBLEM TO BE SOLVED: To suppress pattern noise generated during the rolling of a tire with a tread pattern in which a plurality of kinds of pattern elements are arranged adjacent to each other along the whole periphery in the peripheral direction of the tire in at least a partial tire tread part to form a pattern design row. SOLUTION: When grounding length in grounding condition specified by JATMA is L, a position on the pattern design row D apart from a start end Siof the pattern element Piin the pattern design row D by distance equivalent to reference length L is a corresponding position Xj, and the pattern element to which the corresponding position Xjbelongs is a corresponding pattern element Pj, at least either of pitch lngth of the pattern element Piin the pattern design row D and arrangement order of the pattern element Piis adjusted so that the corresponding position Xjapproaches the vicinity of the center of the corresponding pattern element Pj.
