Two-wheeled automotive vehicle tire

摘要

Rolling resistance performance, high-speed-durability performance, and cornering performance are simultaneously realized at high levels. A two-wheeled automotive vehicle tire (1) includes a tread portion (2) having an outer surface (2S) that extends so as to be curved such that the outer surface (2S) 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´1b) 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.
