A motorcycle tire having a rotation direction specified, the motorcycle tire including one or more land portions (5a, 5b) on a center part of the tire occupying 50% of a length of the tire on a tread surface of the tire along a periphery of the tread surface, the one or more land portions (5a, 5b) divided by a plurality of width direction grooves (3a, 3b) extending in a tire width direction and a plurality of circumferential direction grooves (4a, 4b, 14a, 14b) extending in a tire circumferential direction, the center part having an equatorial plane of the tire as a center of the center part, wherein at least one of the land portions is configured such that, in a circumferential cross-section of the tire, wherein a reference line is a section perpendicular to a shortest virtual line connecting a first boundary and a second boundary, the first boundary being between a bottom part of the plurality of width direction grooves (3a, 3b) and one side wall of the land portion at a kick-out side in the rotation direction of the tire, the second boundary being between the bottom part of the plurality of width direction grooves (3a, 3b) and other side wall of the land portion at a step-in side in the rotation direction of the tire, both the side walls (50A, 50B) facing the respective width direction grooves (3a, 3b), the bottom parts (u1, u2) being of the width direction grooves (3a, 3b), the section passing through a third boundary between a surface of the land portion and the one side wall of the land portion at the kick-out side in the rotation direction of the tire an inclination angle (θ1) of the side wall at the kick-out side to the reference line is ranged from -10° to 5° inclusive, where a direction of inclination toward the land portion is defined as a negative direction, and the inclination angle (θ1) of the side wall at the kick-out side is smaller than an inclination angle (θ2) of the side wall at the step-in side to a section, among the perpendicular lines, which passes through the boundary between the surface of the land portion and the side wall at the step-in side. at least one of the land portions is configured such that, in a circumferential cross-section of the tire, wherein a reference line is a section perpendicular to a shortest virtual line connecting a first boundary and a second boundary, the first boundary being between a bottom part of the plurality of width direction grooves (3a, 3b) and one side wall of the land portion at a kick-out side in the rotation direction of the tire, the second boundary being between the bottom part of the plurality of width direction grooves (3a, 3b) and other side wall of the land portion at a step-in side in the rotation direction of the tire, both the side walls (50A, 50B) facing the respective width direction grooves (3a, 3b), the bottom parts (u1, u2) being of the width direction grooves (3a, 3b), the section passing through a third boundary between a surface of the land portion and the one side wall of the land portion at the kick-out side in the rotation direction of the tire an inclination angle (θ1) of the side wall at the kick-out side to the reference line is ranged from -10° to 5° inclusive, where a direction of inclination toward the land portion is defined as a negative direction, and the inclination angle (θ1) of the side wall at the kick-out side is smaller than an inclination angle (θ2) of the side wall at the step-in side to a section, among the perpendicular lines, which passes through the boundary between the surface of the land portion and the side wall at the step-in side.
