ABSTRACT:
A radial carcass motor vehicle tire having a cross-section in which the ratio of the section height/overall width is less than 1 and preferably not greater than 0.7 and which is intended to be mounted on a rim provided with bead-seats inclined at an angle of 15.degree. with respect to the rotation axis, is provided with a bead-wire core around which the extremity of the carcass ply or plies, is turned-up from the inside towards the outside. The bead-wire cores are formed of rubberized metallic wires, wound spirally so as to present a polygonal cross-section elongated in the axial direction. The base of the core is inclined at an angle of 15.degree. with respect to the rotation axis. The bead-core has an irregular geometrical section, having its bary-center axially shifted to the outside with respect to the line of the mid-plane of the bead-core base from between 7% to 30% of the axial width of the bead-core base.
