The tire has a radial carcass reinforcement which includes at least one layer of metal reinforcing elements and a crown reinforcement, which is capped radially with a tread. The metal reinforcing elements of at least one layer of the carcass reinforcement are cords with several steel threads that have a weight content of carbon C such that 0.01%≤C<0.4%. The cords exhibit, in the “permeability” test, a flow rate of less than or equal to 20 cm3/min. The thickness of the rubber compound between the inner surface of the tire cavity and the point of a metal reinforcing element of the carcass reinforcement that is closest to the inner surface of the cavity is less than 3.2 mm, and the steel threads have a maximum tensile strength R, expressed in MPa, such that R≥175+930.0-600.ln(d) and R≥1500 MPa.
