A tire comprising a tread having tread edges (TE) 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 (TE) side toward a tire equator (CL) side, wherein: the plurality of sipes include sipes arranged on the tread edge (TE) sides, each of the sipes arranged on the tread edge (TE) sides being shaped so as to consist of, when a plane extending from an open portion (T) of the sipe in a radial direction of the tire in accordance with a shape of the open portion (T) is defined as a reference plane : an extending portion extending in the radial direction of the tire from the open portion (T) 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 (CL), in a central region (CE) located between the regions (SH) in which the sipes arranged on the tread edge (TE) 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 (T) of the width direction sipe in the radial direction of the tire in accordance with a shape of the open portion (T) is defined as a reference plane : an extending portion extending in the radial direction of the tire from the open portion (T) 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 (T) 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 (CL), in a central region (CE) located between the regions (SH) in which the sipes arranged on the tread edge (TE) 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 (T) of the width direction sipe in the radial direction of the tire in accordance with a shape of the open portion (T) is defined as a reference plane : an extending portion extending in the radial direction of the tire from the open portion (T) 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 (T) 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. <EOS>
