Abstract

Pneumatique avec une armature ancrée à au moins une tringle de bourrelet, ladite tringle étant en profilé métallique. Selon l'invention, la tringle 3, vue en section radiale, est essentiellement formée de quatre côtés concourants deux à deux et d'un renfort 34, 35 reliant les deux régions où se rencontrent deux côtés concourants consécutifs, et en ce que cette tringle est disposée dans le bourrelet 1 de façon que ledit renfort forme un angle beta , inférieur à +- 60 degrés avec la bissectrice C issue de l'angle alpha formé par le siège 4 de bourrelet sur la jante et la tangente t1 au rebord de jante 5 adjacent à ce siège, cette bissectrice étant orientée vers l'intérieur du pneumatique, ce dernier étant monté et gonflé.A tire with a reinforcement anchored to at least one bead bead wire, said bead wire being made of a metal profile. According to the invention, the rod 3, seen in radial section, is essentially formed of four concurrent sides two by two and of a reinforcement 34, 35 connecting the two regions where two consecutive concurrent sides meet, and in that this rod is arranged in the bead 1 so that said reinforcement forms an angle beta, less than + - 60 degrees with the bisector C resulting from the angle alpha formed by the bead seat 4 on the rim and the tangent t1 to the rim flange 5 adjacent to this seat, this bisector being oriented towards the inside of the tire, the latter being mounted and inflated.
