Abstract:
A pneumatic tire comprising:a first block row in which a plurality of blocks projecting from an outer circumference of said pneumatic tire are disposed along a tire circumferential direction; and a second block row in which a plurality of blocks projecting from the outer circumference of said pneumatic tire are disposed along the tire circumferential direction, said second block row being parallel to said first block row, wherein a side surface of a leading edge side end portion of each block of said first block row and said second block row is inclined with respect to a tire transverse direction such that an angle, which is formed by the side surface of the leading edge side end portion of each block of said first block row and a tire leading edge side contour line of a ground-contact configuration, and an angle, which is formed by the side surface of the leading edge side end portion of each block of said second block row and the tire leading edge side contour line of the ground-contact configuration, are substantially equal, the side surfaces of the leading edge side end portions of said blocks are separated from adjacent blocks by tire transverse direction lug grooves formed in a tread surface, and for each of said lug grooves, one tire transverse direction end thereof is narrow and another tire transverse direction end thereof is wide.
