Abstract
Tire having a carcass reinforcement anchored to at least one bead ring, the bead ring consisting of a hollow metallic member, is improved due to the fact that the bead ring as seen in radial cross-section is essentially formed of four sides which converge in pairs and of an interior reinforcement connecting the two regions where two consecutive converging sides meet, and due to the fact that the bead ring is arranged in the bead in such a manner that the interior reinforcement forms an angle of less than .+-.60.degree. with the bisector of the angle formed by the bead seat on the rim with the tangent to the rim flange adjacent to said bead seat, the bisector being directed towards the inside of the tire, the latter being mounted and inflated.
