<p>A carcass layer (4) is provided, in which a plurality of cords folded so as to be wound around an annular bead core (2) are coated with rubber. On an outside of this carcass layer (4), a wire chafer (7) in which a plurality of cords are coated with rubber is provided. An outer end portion (7a) in a tire width direction of the wire chafer (7) is extended to an outside in a tire radial direction more than a folded end portion (4a) of the carcass layer (4). An interval between each cord of a folded portion (4b) of the carcass layer (4) and each adjacent cord of the wire chafer (7) thereto is formed so as to be widened toward the outside in the tire radial direction. An inner end portion (7b) in the tire width direction of the wire chafer (7) is located on an outside in a tire radial direction from an intersection (11) of a normal (10) suspended from a curvature center (O) of a flange (9) to an inner end portion (4c) in the tire width direction of the carcass layer (4) and of the inner end portion (4c) in the tire width direction.</p> |
