Abstract
A tire comprising sidewalls joining a crown part to beads that are intended to come into contact with a mounting rim, these sidewalls comprising a carcass reinforcement anchored in each bead to at least one bead wire and having an end in each bead, the bead wire having, seen in meridian cross-section, an outer profile comprising two profile parts, a first part radially to the inside of axial width L, extending between an axially innermost point and an axially outermost part, and a second part radially to the outside between said points. Each bead comprises at least one additional coupling reinforcement in contact with the carcass reinforcement. In each bead and seen in meridian cross-section: the carcass reinforcement is partially wrapped around the bead wire and is such that its end lies axially between the end points of the radially internal profile part of the bead wire; and the additional coupling reinforcement extends the carcass reinforcement so as to be at least partly wrapped around the bead wire, that is to say so as to partly cover at least the radially external profile part of said bead wire.
