Title (EN) TYRE HAVING A REDUCED-WEIGHT BEAD REGION
(FR) PNEUMATIQUE DONT LA ZONE DU BOURRELET EST ALLEGEE
Abstract: front page image
(EN)The invention relates to a tyre with a radial carcass reinforcement formed by a single ply of reinforcement elements, the single ply being turned up around a bead core in such a way as to be anchored in each of the beads. According to the invention, the turn-up of the carcass reinforcement ply and the principal portion of the carcass reinforcement ply are the only plies of reinforcement elements having elongation at break lower than 6% present in the sidewall, and any point of the profile of the outer surface "S" of the tyre between points "F" and "E" is at a distance of less than 1 mm from the spline "P" connecting said first and second points "F" and "E".
(FR)L'invention concerne un pneumatique à armature de carcasse radiale, constituée d'une unique couche d'éléments de renforcement ancrée dans chacun des bourrelets par retournement autour d'une tringle. Selon l'invention, le retournement de la couche d'armature de carcasse et la partie principale de la couche d'armature de carcasse sont les seules couches d'éléments de renforcement dont l'allongement à rupture est inférieur à 6 % présentes dans le flanc et tout point du profil de la surface extérieure "S" du pneumatique entre les points "F" et "E", est à une distance inférieure à 1 mm de la spline "P" reliant lesdits premier et deuxième points "F" et "E".
