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: A tire having two beads and a carcass reinforcement with a main part wrapped within each bead around a bead wire core to form a turned-back portion. Each bead has an additional reinforcement and a filler profiled element extending the bead wire core radially outwards. This filler profiled element has, in any meridian plane, a three exterior sides including a radially inner side, axially inner side and axially outer side, with the axially inner and outer sides converging at a radially outermost point, and is formed of a stack in the radial direction of at least three polymer materials in contact along a contact surface that intersects any meridian plane along a meridian line.
