摘要： A pneumatic tire capable of reducing air column resonance arising from circumferential grooves without changing the shape of unilaterally open-ended lug grooves. Lug grooves 20 are formed in land portions 15, which are defined by the circumferential grooves, and each of the lug grooves 20 consists of a lateral groove portion 21, which extends axially to open at one end into the circumferential groove and communicate at the other end with a sub-groove 12 provided in the land portion 15, and an oblique groove portion 22, which extends in a direction intersecting with the tire axial and circumferential directions to communicate at one end with the sub-groove 12 and terminate at the other end within the land portion 15. Also, the lateral groove portion 21 of the lug groove 20 is provided with a projection 23 protruding toward the tread surface from the bottom of the lug groove 20 and having a height smaller than the height H of the land portion 15 as measured from the bottom of the lug groove 20.
摘要翻译：一种充气轮胎，能够减小由圆周槽产生的空气柱共振而不改变单向开口的横向花纹沟的形状。凸缘槽20形成在由周向槽限定的陆部15中，并且每个横向花纹沟20由横向槽部21构成，该横向槽部21在一端轴向延伸到周向槽中并在另一端连通端部具有设置在陆部15中的副槽12和倾斜槽部22，该倾斜槽部22沿与轮胎轴向和周向相交的方向延伸，以在一端与副槽12连通并终止于另一侧另外，横向槽20的横向槽部21设置有从凸缘槽20的底部向胎面表面突出的突起23，该突起23的高度小于焊盘的高度H 部分15从横向花纹槽20的底部测量。
