Abstract: 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.

Abstract: A pneumatic tire includes a tread portion provided with at least one zigzag main groove extending continuously in a circumferential direction of the tire with a plurality of zigzag corners. The main groove includes a groove bottom and a pair of groove edges. The groove bottom extends in a zigzag manner in the circumferential direction of the tire with a first amplitude. The groove bottom has a width varying periodically so that a maximum width portion and a minimum width portion appear in turn at the zigzag corners. Each of the groove edges extends in a zigzag manner in the circumferential direction of the tire with a second amplitude, wherein the first amplitude is greater than the second amplitude.
