Abstract

To provide a tire with improved operation stability while restricting degradation of noise performance.SOLUTION: A land part 4 of a tread part includes a first edge e1 and a second edge e2 extending in a circumferential direction. In the land part, a plurality of lateral groove-shaped elements 7 extending from a first end 7A positioned on a first edge to a second end 7B positioned at a second edge are formed. The lateral groove-shaped elements are arranged in a tire circumferential direction so that a second end of one lateral groove-shaped element and a first end of another lateral groove-shaped element adjacent to the same in the tire circumferential direction are the same positions in the tire circumferential direction. The lateral groove-shaped elements include the first part on the first end side, the second part on the second end side and a third part between them, and these are inclined in the same direction against tire circumferential direction. Angle θ3 against a tire circumferential direction of the third part is smaller than angle θ1 against the tire circumferential direction of the first part and angle θ2 against the tire circumferential direction of the second part. The third part is longer than a sum of lengths of the first part and the second part.SELECTED DRAWING: Figure 2
