TIRE COMPRISING CABLES FOR REINFORCING THE CASING HAVING LOW PERVIOUSNESS, AND TEXTILE THREADS ASSOCIATED WITH THE CASING REINFORCEMENT

摘要

The invention relates to a tire having a radial casing reinforcement (2), consisting of at least one layer of metal reinforcement elements, including a crown reinforcement (6) that is radially covered by a tread (7) that is joined to two beads via two sidewalls. Said metal reinforcement elements are cables having a flow rate of less than 20 cm³/min in the perviousness test. At least one layer of the casing reinforcement is provided on at least one surface of staple textile threads (12), one end (17) of a textile thread being positioned on the turn-up (5) of the casing reinforcement around rods (4), and the other end (13) being radially inside the orthogonal projection (9) of the shoulder end (11) on said surface of said layer of the casing reinforcement.
