PURPOSE:To improve lateral rigidity of the captioned tire while keeping wear resistance, road keeping property, and a highspeed running property by properly selecting structures, arrangements and materials of a carcass reinforcement layer and a braker, in a radial structure of a motorcycle tire. CONSTITUTION:A tire 1 comprises a tread part 2, a side wall part 3 radially extending from both ends of said tread part toward the inside thereof, and a bead part 4 located at the radially inner end part of the tire. Then, the carcass 5 is formed by two plies, and both ends thereof are folded back around a bead core 6 from the inside to the outside of the tire. The cord of the carcass 5 is arranged in parallel to the radial direction of the tire 1. In addition, a braker is arranged with a low cord angle with respect to the tire peripheral direction in the radially outward direction of the carcass 5. Further, bands 10, 11 having the cords arranged in parallel to the tire peripheral direction are provided at the central portion and both ends of the braker outside it. |
