Abstract (en)
[origin: WO2017037226A1] The invention relates to a pneumatic tire (1) having a radial carcass reinforcement (2) consisting of at least one ply of metal reinforcement elements, said pneumatic tire comprising a top reinforcement (5) which is radially covered with a tread (6), said tread being joined to two beads (4) via two sidewalls. According to the invention, the metal reinforcement elements of at least one ply of the carcass reinforcement are cords consisting of a plurality of steel wires that have a percentage by weight of carbon C of 0.01% < C < 0.4%, said wires having a maximum flow rate of 20 cm3/min in the permeability test; furthermore, the thickness of the rubber mixture between the inner surface of the tire cavity and that point of a metal reinforcement element of the carcass reinforcement which is closest to said inner surface of the tire cavity is less than 3.2 mm, and the steel wires have a tensile strength R, in MPa, such that R > 175 + 930.C - 600.1n(d) and R > 1500 MPa.
