摘要： A pneumatic tire includes a tread portion provided with a land portion with a plurality of lateral grooves extending across the land portion. Each lateral groove includes a main portion with a width equal to or more than 2.0 mm and a sipe portion extending radially inwardly from a bottom of the main portion. The main portion includes a first wall located on a first side in a circumferential direction and a second wall located on a second side in the circumferential direction. The sipe portion includes a first sipe wall located on the first side and a second sipe wall located on the second side. The lateral grooves include a first lateral groove having the first wall being continuous to the first sipe wall smoothly and a second lateral groove having the second wall being continuous to the second sipe wall smoothly.

摘要： A tire comprises a tread portion 2. The tread portion 2 comprises a plurality of blocks each comprising a first longitudinal edge 18 and a second longitudinal edge 19 extending in a tire circumferential direction, and a ground contacting surface defined therebetween. The blocks include a first block 20 having a first narrow groove 21 provided in the ground contacting surface thereof. The first narrow groove 21 extends from a first end 21a on the first longitudinal edge 18 toward a center 24 in a tire axial direction of the first block 20 and curves within the ground contacting surface and reaches a second end 21b on the first longitudinal edge 18 so as to extend in a laterally oriented V-shape.

摘要： A pneumatic tire includes a tread portion provided with at least one zigzag main groove extending continuously in a circumferential direction of the tire with a plurality of zigzag corners. The main groove includes a groove bottom and a pair of groove edges. The groove bottom extends in a zigzag manner in the circumferential direction of the tire with a first amplitude. The groove bottom has a width varying periodically so that a maximum width portion and a minimum width portion appear in turn at the zigzag corners. Each of the groove edges extends in a zigzag manner in the circumferential direction of the tire with a second amplitude, wherein the first amplitude is greater than the second amplitude.
摘要翻译：一种充气轮胎包括：胎面部，其设置有至少一个锯齿形主槽，该锯齿形主槽在轮胎的圆周方向上连续延伸有多个锯齿形拐角。主槽包括槽底和一对槽边。凹槽底部以第一幅度在轮胎的圆周方向上以锯齿形的方式延伸。凹槽底部具有周期性变化的宽度，使得最大宽度部分和最小宽度部分在锯齿形拐角处依次出现。每个槽边缘以锯齿状方式在轮胎的圆周方向上以第二幅度延伸，其中第一幅度大于第二幅度。
