Tyre in the shape of a torus open radially on the inside with an inner wall and an outer wall, the inner wall being at least partially covered with a sealing layer (50), a crown, two side walls and two beads, a crown reinforcement and a carcass reinforcement (60) which is anchored in the two beads and extends at least from the beads as far as the crown, characterized in that the sealing rubber (50) is, at least in part, covered with a layer of self-sealing product (55), and in that, with each bead having an annular reinforcing structure (70), the annular reinforcing structure comprises several windings of a single metal wire (72, 73) which are arranged axially side by side in several radially superposed layers so as to define a hexagonal cross section. |
