Abstract:
A tire has a radial carcass reinforcement having a bead, the seat of which is inclined towards the outside, the bead heel axially to the inside and reinforced by at least one reinforcement element, the bead toe axially to the outside and having a profiled element of rubber mix in the form of a wedge defined by two sides, the mix having a Shore A hardness greater than the Shore A hardness of the rubber mixes radially above, wherein the reinforcement winds around the annular element to form an upturn, the end of which is located axially to the outside of a straight line P2 perpendicular to the axis of rotation and passing through the center of gravity of the meridian section of the element, and axially to the inside and radially to the outside of the straight line P1 supporting the radially outer side of the profiled element.
