TIRE COMPRISING CARCASS REINFORCEMENT WIRES HAVING DIFFERENT PERVIOUSNESSES

摘要

A tire with a radial carcass reinforcement made up of at least one layer of metal reinforcing elements, the tire comprising a crown reinforcement itself capped radially with a tread, the tread being connected to two beads via two sidewalls. At least 70% of the metal reinforcing elements of at least one layer of the carcass reinforcement are non wrapped cables which, in what is known as the air-wicking test, display a flow rate of less than 2 cm3/min, and at least 10% of the metal reinforcing elements of the at least one layer of the carcass reinforcement are cables which, in what is known as the air-wicking test, display a flow rate of greater than 4 cm3/min.
