摘要： Radial tires for motorcycles comprising a tread portion, side wall portions, bead portions, a carcass, a breaker, and optionally a reinforcing cord layer arranged outside the carcass and extending from one bead portion to the other bead portion and bead apexes made of a hard rubber, said tread portion having a plurality of longitudinal grooves in the circumferential direction at an angle of at least 5.degree. with respect to the cords of the most outer ply of the breaker. The motorcycle radial tires of the invention have an improved transverse stiffness at the side wall portions and moreover do not cause cracks at the bottom of the grooves in the tread portion.
