MOTORCYCLE TIRE

A tread surface of the tire includes a center portion C and a pair of shoulder portions S. A contour line of the tread surface is 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 surface is not less than 50%. A ratio of the degree of curvature of the center portion C to the width TW of the tread surface is not greater than 70%.
