Resistance to unseating of a tire operating at low pressure is achieved by a tire comprising at least one bead having an axial width at the seat D comprising at least one main circumferential reinforcing element (22) of which the radially innermost point (222) is at a radial distance Z and at an axial distance Y from the radially innermost point (211) of the bead, and such that Y/D is at least equal to 0.5 and Z/D is at most equal to 0.4. This same bead comprises at least one bead layer (23) surrounding the bead filler rubber (21) and such that its axially outermost end (231) is radially on the outside of the end (311) of the carcass layer (31) and it also comprises at least one additional circumferential reinforcing element (24), radially on the inside of the radially outermost point (223) of the main circumferential reinforcing element (22).
