A tread surfaceof the tireincludes a center portion C and a pair of shoulder portions S. A contour line of the tread surfaceis divided into ten parts. Among the ten parts, two parts including an equator PC are represented by arcs, and two parts including ends PE of the tread surface, respectively, are represented by arcs. A degree of curvature of each shoulder portion S is higher than a degree of curvature of the center portion C. A ratio of the degree of curvature of the shoulder portion S to a width TW of the tread surfaceis not less than 50%. A ratio of the degree of curvature of the center portion C to the width TW of the tread surfaceis not greater than 70%.

Tire for motorcycle

A pneumatic tire includes a tread, two circumferentially extending annular bead regions, a carcass structure, and an overlay ply. The tread is rotatable about an axis and contacts a road surface. The tread further has an equatorial plane intersecting the axis at 90&#xb0;. The carcass structure extends between the tread and the bead regions. The carcass structure supports the tread about the axis. The carcass structure includes two or more carcass plies having reinforcing cords oriented to cross at opposite angles of 20&#xb0; to 65&#xb0; with respect to the equatorial plane. The overlay ply extends circumferentially and extends radially between the carcass structure and the tread. The overlay ply includes cords oriented between &#x2212;5&#xb0; and +5&#xb0; relative to the equatorial plane.
