Bead wire for a tire, tire and manufacturing method

A bead wire for a tire substantially of revolution about an axis comprising several windings of at least one wire which are arranged axially next to one another over N layers radially superposed on one another, comprising:

• a basic hexagonal bead wire comprising:
• a radially external layer of N1 windings,
• a radially internal layer of N1 windings,
• two axially and radially external lateral rows of N2 windings axially opposite one another,
• two axially external and radially internal lateral rows of N2 windings axially opposite one another, with N1=N2 +1 or N1=N2, and
• two junctions each one formed by a winding that an axially and radially external lateral row and an axially external and radially internal lateral row have in common, each winding in common forming each junction having no winding of the bead wire axially on the outside of it;
• and
• additional windings comprising:
• axially external and radially internal additional windings, the axially external and radially internal additional windings consisting exclusively of two pairs of axially external and radially internal additional lateral rows, each of the two pairs of axially external and radially internal additional lateral rows having a radially internal winding radially aligned with the radially internal layer of the basic hexagonal bead wire.
