Summary: | The bead wire (52) for a tyre is substantially rotationally symmetric around an axis comprising several windings of at least one wire arranged axially beside one another over N layers Ci radially superimposed on top of one another. The bead wire (52) for a tyre comprises a base hexagonal bead wire (56) comprising: - radially external and internal layers (C'sup, C'inf) of N1 windings, - two axially and radially external lateral alignments (F1, F2) of N1 windings, - two axially external and radially internal lateral alignments (F3, F4) of N1 windings. The bead wire (52) for a tyre comprising a winding (E3.1, E4.1) for axial continuation of the radially internal layer (C'inf). The bead (52) for a tyre comprising an additional layer (Ca3) of N2 windings forming the radially external layer of the bead (52) for a tyre (10). |
