A RUBBER COMPOSITION

A rubber composition, which allows a sufficient scorch time while being maintaining or improving the curing time, the breaking energy performance, the performance of permeability to oxygen and the hysteresis performance, is based on at least an elastomer matrix, a reinforcing filler, a plasticizing agent and a crosslinking system. The plasticizing agent comprises a hydrocarbon resin comprising more than 0.0 phr and less than 20 phr of a tackfying resin, and the crosslinking system comprises a vulcanizing agent comprising more than 0.0 phr and less than 10 phr of a sulfur donor comprising N,N′-Caprolactam disulfide.
