The present disclosure relates to tires, at least one internal layer of which exhibits good mechanical properties and reduced rolling resistance, the said internal layer comprising a rubber composition based on at least 80 to 100 phr of an isoprene elastomer, a reinforcing filler predominantly comprising carbon black, 1 to 45 phr of reinforcing resin, a salt of an alkaline earth, alkali or lanthanide metal, and a crosslinking system.

Tire provided with an inner layer made from at least an isoprene elastomer, a reinforcing resin and a metal salt

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.

Tire comprising a carcass reinforcement layer having improved endurance properties

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 m/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.

Rubber composition comprising a specific reinforcing filler

A semi-finished product or tire comprises a metal reinforcing element embedded in a rubber composition comprising a compound of formula (I): where X and Y represent, independently of one another, an alkali metal or alkaline earth metal cation.
