    摘要： A pneumatic tire for a motorcycle capable of increasing braking performance and high-speed turning performance while securing riding comfortableness. In the pneumatic tire, a semi-radial cross-carcass (16) is used to secure minimum rigidity and riding comfortableness, a belt layer (26) in the form of a cross-belt layer is installed at the crown part of the carcass, and a radial reinforcing band layer (22) in which a plurality of radially extending reinforcement cords (24) are arranged is installed on the inside of a tread end part. Since the radial reinforcing band (22) is disposed, the section bend rigidity of the crown part (bend rigidity in the lateral direction of the tire) is increased. Also, since the reinforcement cords (24) of the radial reinforcing band layer (22) restrain the radial elongation of a pantograph (of diamond shape) formed of a reinforcement cord (11) formed of two sheets of carcass plies, a large reinforcement effect can be provided. In addition, since the radial reinforcing band layers are not added to a tread end part, a high turning performance can be provided.

    摘要： Tyre comprising a reinforcing structure of the carcass type, anchored on each side of the tyre into a bead the base of which is intended to be mounted on a wheel rim seat, each bead being extended radially outwards by a sidewall, meeting a tread, and comprising, under the tread, a crown reinforcing structure consisting at least of two working plies, the reinforcing elements of which are identical in nature. In a given circumferential plane, the rigidity in extension per unit width of a first working layer measured in the main direction of the reinforcing elements is strictly greater than the rigidity in extension per unit width of a second working layer measured in the main direction of the reinforcing elements, the second working layer being radially further from the carcass structure than said first working layer.

    摘要： A radial pneumatic tire (10) has a pair of bead cores (26), a carcass (30) having a carcass ply (40) extending between and turned up around the bead cores (26) from the axially inside to the outside to form a pair of turnup ends (44,44'); a rubber tread (12) disposed radially outside the carcass (30); a belt structure (36) having a first belt ply (37) and a second belt ply (39) disposed adjacently between the carcass (30) and the tread (12). Each of the turned up ends (44,44') of said carcass ply (40) extends radially outward overlying at least a portion of one or both of the at least first and second belt plies (37,39). The tire (10) is manufactured by shaping a carcass (30) and applying a belt reinforcing structure (36) to the carcass (30) and then turning up the carcass ends (44,44') over at least a portion of the belt reinforcing structure (36) along each respective lateral edge of at least one belt layer (37), preferably covering all the lateral edges of two or more belt layers (37,39).
