Abstract
An object of the present invention is to provide a tire possessing improved wear resistance by optimizing configurations of block land portions. The tire is configured such that, in at least two adjacent block land portion arrays 5 sandwiching a circumferential groove 2, adjacent block land portions 4 constituting the block land portion arrays 5 are arranged so as to be positionally displaced from each other in the tire circumferential direction; and a distance d2 between the block land portions adjacent in the tire width direction is shorter than a distance d1 between the block land portions adjacent in the tire circumferential direction. A groove portion 8 between the block land portions adjacent in the tire width direction extends obliquely with respect to the tire width direction and the tire circumferential direction. Further, plural sets each formed by at least two adjacent block land portion arrays 5 sandwiching the circumferential groove 2 are arranged; and, among the block land portions arrays 5, an inclination angle θ1 of an extending direction of the groove portion 8B between the block land portions adjacent in the tire width direction of block land portion arrays 5 loca…
