摘要： A tire comprises a tread portion (2). The tread portion (2) comprises a plurality of blocks each comprising a first longitudinal edge (18) and a second longitudinal edge (19) extending in a tire circumferential direction, and a ground contacting surface defined therebetween. The blocks include a first block (20) having a first narrow groove (21) provided in the ground contacting surface thereof. The first narrow groove (21) extends from a first end (21a) on the first longitudinal edge (18) toward a center (24) in a tire axial direction of the first block (20) and curves within the ground contacting surface and reaches a second end (21b) on the first longitudinal edge (18) so as to extend in a laterally oriented V-shape.
