Summary: | The tire has a radial carcass reinforcement which includes at least one layer of metal reinforcing elements. The tire also has a crown reinforcement, itself capped radially with a tread. The tread is joined to two beads via two sidewalls. The metal reinforcing elements of at least one layer of the carcass reinforcement are cords include several steel threads having a weight content of carbon C such that 0.01%≤C<0.4%. The cords exhibit, in the "permeability" test, a flow rate which is strictly greater than 20 cm3/min, and 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. |
