To provide a two-wheeled motor vehicle tire which can improve rim assembly performance while maintaining operation stability performance.SOLUTION: A bead core 5 includes, on a first transverse plane, a plurality of bead wires 10 including an outer peripheral bead wire group 12, and a coating rubber 11. When an area of a maximum closed region 12A is represented by Sa and a total area of the coating rubber 11 in the closed region is represented by Sb in the outer peripheral bead wire group 12, the total area Sb is 10% to 40% of the area Sa. A bead outer surface includes a rim flange opposite face extending between a first point and a second point. The rim flange opposite face includes a first circular arc part with a curvature radius of 12.5 mm or less.SELECTED DRAWING: Figure 2
