[Object] Rolling resistance performance, high-speed-durability performance, and cornering performance are simultaneously realized at high levels. [Solution] A two-wheeled automotive vehicle tire 1 includes a tread portion having an outer surface that extends so as to be curved such that the outer surface is convex outward in the tire radial direction, and is arc-shaped. A tread rubber 2G includes a center rubber CR, shoulder rubbers SH, and middle rubbers MD. The center rubber CR includes a center cap layer CRc and a center base layer CRb. A loss tangent tan delta1b of the center base layer CRb and a width L1b thereof in the tire axial direction are each limited so as to be set within a predetermined range.
