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

The crosslinkable rubber composition comprises a first elastomer consisting of polybutadiene having a Mooney plasticity ranging from 40 to 70 Mooney units, the content of the first elastomer being strictly greater than 50 phr, a second elastomer, and a carbon black having a specific surface area within a range of values extending from 15 m/g to 25 m/g and an oil adsorption number of compressed sample (COAN) within a range of values extending from 65 ml/100 g to 85 ml/100 g.
