摘要： A pneumatic tire improved in on-ice performance and on-snow performance in good balance. The pneumatic tire includes a tread portion extending in a tire circumferential direction and forming a ring shape, a pair of sidewall portions on both sides of the tread portion, respectively, and a pair of bead portions on inner sides of the sidewall portions in a tire radial direction, respectively. The tread portion includes a plurality of longitudinal grooves extending in the tire circumferential direction and a plurality of lateral grooves extending in a tire width direction. The longitudinal and lateral grooves define a plurality of block rows each including a plurality of blocks. Each of the plurality of blocks included in at least one of the block rows includes at least three closed grooves including at least one first closed groove and at least one second closed groove.

摘要： A pneumatic tire has a good balance between on-ice and on-snow performances. The tire includes a tread portion having longitudinal and lateral grooves defining block rows. Each block in the block rows includes sipes. A length of each block in the first and second block rows is not less than 1.5 times and not more than 2.5 times a length of each third block row block. A width of each second block row block is larger than a width of each first block row block. The lateral grooves defining the first and second block row blocks are offset in the tire circumferential direction by not less than 0.2 times and not more than 0.8 times the length of each first block row block. The lateral grooves defining the second and third block row blocks communicate with each other while inclining in the same direction.
摘要翻译：充气轮胎在冰上和雪上的表现之间有很好的平衡。轮胎包括具有限定块排的纵向和横向槽的胎面部分。块行中的每个块都包括刀槽。第一和第二块行中的每个块的长度不小于每个第三块行块的长度的1.5倍且不大于2.5倍。每个第二块行块的宽度大于每个第一块行块的宽度。限定第一和第二块排块的横向槽在轮胎周向方向上偏移不小于每个第一块排块的长度的0.2倍且不大于0.8倍。限定第二和第三块排块的横向槽在相同方向倾斜的同时相互连通。
