TYRE HAVING LOW-PERMEABILITY CARCASS REINFORCEMENT CABLES, AND TEXTILE CORDS ASSOCIATED WITH THE CARCASS REINFORCEMENT

摘要

The invention relates to a tyre with a radial carcass reinforcement (2) consisting of at least one layer of metallic reinforcing elements (7), said tyre comprising a crown reinforcement (5) which is itself covered radially by a tread, said tread being joined to two beads by two sidewalls. According to the invention, the metallic reinforcing elements (7) of at least one layer of the carcass reinforcement are unhooped cables which exhibit in the so-called permeability test a flow rate of less than 20 cm/min and at least one layer of the carcass reinforcement (2) being provided on at least one face with at least one layer of textile cords (10) of rectilinear orientation and said textile cords (10) forming an angle with the direction of the metallic reinforcing elements of said layer or layers of the carcass reinforcement of more than 10°.
