    Abstract: Tire having a radial carcass reinforcement anchored in each bead by an upturn around a bead wire, reinforced by at least one layer of reinforcing elements turned up around the bead wire, one end of said at least one layer of reinforcing elements being axially on the outside of the carcass reinforcement upturn and radially on the inside of the end of said upturn, the other end turned up around the bead wire being axially on the inside of the carcass reinforcement. The reinforcing elements are non-wrapped metal cords with saturated layers, having, in a permeability test, a flow rate of less than 5 cm3/min and the distance between the end, axially on the outside of the carcass reinforcement upturn, of said at least one layer of reinforcing elements turned up around the bead wire and the end of the carcass reinforcement upturn is less than 5 mm.

    Abstract: The invention relates to a tire having a radial carcass reinforcement, consisting of at least one layer of reinforcing elements anchored in each of the beads by an upturn around a bead wire, said carcass reinforcement upturn being reinforced by at least one layer of reinforcing elements or stiffener, the radially outer end of which is radially on the outside of the end of the upturn.According to the invention, the reinforcing elements of at least one stiffener are non-wrapped metal cords with saturated layers, having, in what is called the permeability test, a flow rate of less than 5 cm3/min, the radially inner end of said stiffener being radially on the inside of the point of the bead wire which is radially closest to the axis of rotation and the modulus of elasticity of the polymer blends of the calendering layers of the carcass reinforcement being less than or equal to 8 MPa.
