Abstract: A tire with a radial carcass reinforcement, made up of at least one layer of metal reinforcing elements inserted between two skim layers of elastomer compound containing a reinforcing filler made up of at least carbon black. The tensile elastic modulus at 10% elongation of at least the skim layer closest to the internal cavity of at least the carcass reinforcement layer closest to the internal cavity is less than 8.5 MPa and at least the said skim layer closest to the internal cavity of at least the carcass reinforcement layer closest to the internal cavity has a macrodispersion value Z greater than 85.

Abstract: A rubber composition has an improved rolling resistance and is based on at least a diene elastomer comprising mainly at least one isoprene elastomer; a reinforcing filler comprising from 15 to 70 phr of carbon black having a BET specific surface area of less than 70 m2/g, and/or a COAN of less than 90 ml/100 g, and from 5 to 20 phr of silica; a salt of an alkaline-earth, alkali or lanthanide metal; and a crosslinking system; in which composition the carbon black to silica ratio is greater than 1.
