Abstract: A tire 1 according to the present invention comprises: a circumferential groove 12 formed in a tread portion; a land portion 22 divided by the circumferential groove 12; and transverse grooves formed in the land portion. The transverse grooves comprise a first transverse groove 32 dividing the land portion into several blocks, and a second transverse groove 51 dividing a block 42 divided by the first transverse groove into a first block portion 61 and a second block portion 62. A groove depth of the circumferential groove contacting the second block is smaller than the groove depth of the circumferential groove contacting the first block.

Abstract translation: 根据本发明的轮胎1包括：形成在胎面部分中的周向槽12; 由周向槽12分隔的陆部22; 以及形成在陆部中的横向槽。 横向槽包括将陆部分割成几个块的第一横向槽32和将由第一横向槽划分的块42划分成第一块部分61和第二块部分62的第二横向槽51。 接触第二块的圆周槽小于与第一块接触的周向槽的槽深度。

Abstract: A land portion of a pneumatic tire 1 comprises a land portion 10 having groove wall 10a a second land portion 20 having a groove wall 20a. The groove walls 10a, 20a meander. A groove width of a main groove 50 changes at a predetermined repetition cycle. The main groove 50 includes: a wide groove portion 50A having a predetermined width; and a narrow groove portion 50B which is continuous with the wide groove portion and which is narrower than the predetermined width. A relationship of θ1>θ2 is satisfied where θ1 refers to an angle formed between a tire normal line RL and the groove wall 10a or the groove wall 20a forming the wide groove portion 50A and θ2 refers to an angle formed between the tire normal line RL and the groove wall 10a or the groove wall 20a forming the narrow groove portion 50B.
