  "textContent": "Provided is a tire exhibiting improved wear resistance, partial wear resistance, and traction performance on the wet road surface. The tire has block land portion arrays 5 defined on a tread portion 1. Between two block land portion arrays 5 located adjacent to each other while sandwiching a circumferential groove 2, a block land portions 4 constituting the block land portion arrays are arrange so as to be positionally displaced from each other, and a groove portion 6 located between the block land portions adjacent in the tire width direction extends obliquely with respect to tire width direction and the tire circumferential direction. At this time, a distance d 2 between the block land portions adjacent in the tire width direction is shorter than a distance d 1 between the block land portions adjacent in the circumferential direction. In the block land portion arrays 5 adjacent in the tire width direction, an inclined angle ± of a side wall 9 of the block land portion 4 located on the groove portion 6 side with respect to the tire circumferential direction is larger than an inclined angle ² of the other side wall 10 located on the opposite side to said groove portion 6 with respect to the tire circumferential direction.",
