Abstract: This tyre includes a toroid-shaped carcase 1, a ply interposed about a region at the top of the carcase, a linkage 5 and a reinforcement of the part forming the bead of the tyre, formed by a main bead chafer strip 3 made up of cables formed of aromatic polyamide fibres, and an auxiliary bead chafer strip 4 including at least two external layers of steel cord 4-1, 4-2 and at least two internal layers of steel cord 4-3, 4-4, the auxiliary bead chafer strip 4 having a triangular lattice structure defined by three layers of steel cord out of the four layers, and so that the steel cords of the two outer layers cross over one another with respect to the meridian plane of the tyre and the steel cords of the two internal layers of steel cords cross over one another with respect to the meridian plane. Application particularly to aircraft tyres.
