The invention relates to a tire with a radial carcass reinforcement, the said tire comprising a crown reinforcement itself capped radially by a tread. According to the invention, the metal reinforcing elements of the carcass reinforcement are wrapped cords which, in the test referred to as the permeability test, return a flow rate of less than 20 cm3/min and over the whole of the meridian profile of the tire, the thickness of rubber compound between the interior surface of the tire cavity and a point of a metal reinforcing element of the carcass reinforcement is between 1.0 mm and 3.0 mm.
