    摘要： A tire P with a radial carcass reinforcement (1), intended for mounting on a rim J at least one of whose seats (42) is inclined outwards and is extended axially on the outside by a hump (41) of small height, said hump comprising an axially outer wall (411), and comprising two sidewalls (8) and at least one bead (5) with a heel axially on the inside and a bead toe axially on the outside, said bead (5) being provided with a protective rib T extending in the circumferential direction and axially further away from the equatorial plane than the axially outer wall (411) of the hump (41) of the rim in order to protect said rim J, the profile of the lower face BC connecting the axially outer face AB of the protective rib T and the profile of the bead (5) being totally located radially outside a virtual segment whose ends are on the one hand the radially innermost point B of the axially outer face AB of the rib T, and on the other hand the last point C′ of the tire bead which is in contact with the hump of the rim.

    摘要： A tire with radial carcass reinforcement having beads with a heel portion on an axially inner side and a toe portion on an axially outer side includes two carcass reinforcement plies for tension in higher sidewall tires. The bead includes at least one bead wire coated with a rubber mix, a wedge formed of a rubber mix disposed axially outward of the at least one bead wire, and at least one rubber filler located axially and radially outward of the bead wire and wedge. The wedge is defined by two sides extending at an acute angle axially from an apex A located beneath the section of the at least one bead wire, the rubber mix forming the wedge having a Shore A hardness of at least 65 and greater than the Shore A hardness of the at least one rubber filler. According to one embodiment, a carcass reinforcement includes two plies, a first radial reinforcement ply wound on the at least one bead wire to form a first upturn, as viewed in meridian section, the reinforcement ply is wound about said bead wire passing from the heel to the toe of said at least one bead, the first upturn engaging the radially outer side the wedge and, a second radial reinforcement ply wound on said at least one bead wire, wherein, when viewed in meridian section, the second reinforcement ply is disposed in parallel to the first radial reinforcement ply in a sidewall area of the tire and is wound about said bead wire passing from the heel to the toe of said at least one bead with a second upturn extending into engagement with the radial inner side of the wedge.
