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%.
