The inner wall is covered at least in part with an airtight layer, and the airtight layer is covered at least in part with a layer of a self-sealing product. Each of the beads includes an annular reinforcing structure, with each annular reinforcing structure being formed of a plurality of windings of a single metal thread. The windings are arranged in a plurality of radially superposed layers, with each layer having a group of the windings arranged axially in a side by side manner, such that the superposed layers have a hexagonal cross section.
