A tire comprising a tread having tread edges and a tread surface on which tread surface a plurality of sipes are arranged in a manner spaced from each other in a circumferential direction of the tread, each of the sipes extending forward in a tire rotation direction from either tread edge side toward a tire equator side, wherein: the plurality of sipes include sipes arranged on the tread edge sides, each of the sipes arranged on the tread edge sides being shaped so as to consist of, when a plane extending from an open portion of the sipe in a radial direction of the tire in accordance with a shape of the open portion is defined as a reference plane: an extending portion extending in the radial direction of the tire from the open portion along the reference plane; and a protruding portion protruding forward in the tire rotation direction from the reference plane and returning to the reference plane via a bend, wherein: the tire further comprises a plurality of width direction sipes extending in a width direction crossing a tire equator, in a central region located between the regions in which the sipes arranged on the tread edge sides are disposed, wherein: each of the width direction sipes is shaped so as to consist of, when a plane extending from an open portion of the width direction sipe in the radial direction of the tire in accordance with a shape of the open portion is defined as a reference plane: an extending portion extending in the radial direction of the tire from the open portion along the reference plane; and a protruding portion protruding backward in the tire rotation direction from the reference plane and returning to the reference plane via a bend, and wherein: the sipes are cuttings with a width of 0.1 mm to 0.4 mm. an extending portion extending in the radial direction of the tire from the open portion along the reference plane; and a protruding portion protruding forward in the tire rotation direction from the reference plane and returning to the reference plane via a bend, wherein: the tire further comprises a plurality of width direction sipes extending in a width direction crossing a tire equator, in a central region located between the regions in which the sipes arranged on the tread edge sides are disposed, wherein: each of the width direction sipes is shaped so as to consist of, when a plane extending from an open portion of the width direction sipe in the radial direction of the tire in accordance with a shape of the open portion is defined as a reference plane: an extending portion extending in the radial direction of the tire from the open portion along the reference plane; and a protruding portion protruding backward in the tire rotation direction from the reference plane and returning to the reference plane via a bend, and wherein: the sipes are cuttings with a width of 0.1 mm to 0.4 mm. an extending portion extending in the radial direction of the tire from the open portion along the reference plane; and a protruding portion protruding backward in the tire rotation direction from the reference plane and returning to the reference plane via a bend, and wherein: the sipes are cuttings with a width of 0.1 mm to 0.4 mm.
