摘要： A tire apparatus for driving a vehicle allows the vehicle to be driven during periods of both low tire pressure and normal tire pressure. The tire apparatus has a tire that has a tread section. The tire has a pair of side walls that are located adjacent to the tread section. A first bead is located at an end of one of the side walls, and a second bead is located at an end of the other side wall. A wheel is also present that has a rim with a first bead seat and a second bead seat. The wheel is configured for attachment to the vehicle. The wheel has a support member for engaging the tire during periods of low tire pressure. At least one of the first and second bead seats has a plurality of friction members to prevent relative rotational movement between the tire and the rim.

摘要： A process for demounting a tire P, and a tread-bearing support S internal thereto, from an integral mounting rim J, which comprises first and second rim seats, the two rim seats being inclined towards the outside and extended axially to the outside by projections of low height. The process includes the steps of inserting, into a lubricated gap between the toe of the first bead Bo and the corresponding rim seat, a demounting insert I in the form of a portion of a circular ring of triangular meridian section of small dimensions, and then ejecting the first bead Bo from the rim J before or simultaneously with the ejection of the tire/support assembly.

摘要： A tire having at least one bead seat inclined towards the outside and a radial carcass reinforcement (1) wound within said bead around a bead wire (2) from the heel to the toe of the bead B to form an upturn (10), the edge of which, viewed in meridian section, is located on the radially outer face (31) of a profiled element (3) of rubber mix. The profiled element is located axially and externally adjacent to the bead wire (2), and has, viewed in meridian section, the shape of a drop of water with an apex A located beneath the section of the bead wire (2), and a Shore A hardness greater than the Shore A hardness(es) of the rubber mixes (6, 7) located axially and radially above the bead wire/profiled element assembly. The carcass reinforcement upturn (10) is extended by a reinforcement armature (11) which surrounds the profiled element (3).
