PNEUMATIC OF WHICH THE CARCASS REINFORCEMENT IS REINFORCED BY A LAYER OF REINFORCING ELEMENTS IN THE BOURRELET AREA

摘要

The invention relates to a tire with a radial carcass reinforcement, consisting of at least one layer of reinforcing elements anchored in each of the beads by turning around a bead wire, said turning of the carcass reinforcement being reinforced by at least one. layer of reinforcing or stiffening elements. According to the invention, the reinforcing elements of at least one stiffener are non-wrapped metal cables with saturated layers exhibiting in the so-called permeability test a flow rate less than 5 cm3 / min and at least one layer of elastomeric mixture present at least partially in the surface of a zone S, in a meridian plane, is an elastomeric mixture based on natural rubber or synthetic polyisoprene and a reinforcing filler conferring high cohesion.
