Abstract: The invention relates to pneumatic tires for a motor vehicle comprising a multi-layer carcass. Said multi-layer carcass extends between two bead rings, a set of bracing plies provided between the layers of the carcass and a tire tread, and rubber reinforcement layers arranged in the side wall areas which support the tire when it is deflated. The invention is characterized in that a first rubber reinforcement layer is arranged radially within a first carcass layer and a second rubber reinforcement layer is arranged between the first carcass layer and a second carcass layer. The two rubber reinforcement layers extend from the bead filler area to a position under the edge area of the bracing plies. The two rubber layers vary in thickness across the height of the side walls.

Abstract: A tire with a form ratio H/S between 0.3 and 0.8 has a carcass reinforcement (1) which is covered radially by a quasi-cylindrical crown reinforcement (3) and which is tangential at T to a holding circle C. The common tangent at T to the circle C and to the meridian profile of the carcass (1) makes an angle &agr; of between +20° and −80° with respect to a line parallel to the rotation axis and passing through the tangency point T. In its portion located between the tangency point T and the point E of greatest axial width, the carcass reinforcement (1) is provided with a reinforcement armature (6) of circumferentially non-extensible elements. Viewed in meridian cross-section and when the tire is fitted and inflated to the recommended pressure, the carcass (1) has a meridian profile consisting of four circular arcs configured to improve the endurance of the tire while improving its rolling resistance.
