Abstract
A rubber composition is based on at least one diene elastomer, a reinforcing filler, a crosslinking system and a hydrocarbon-based resin. The hydrocarbon-based resin has a number-average molecular weight (Mn) of between 700 and 1000 g/mol, an average molecular weight Mz of greater than 6000 g/mol and a polydispersity index (PI) of greater than 2.4.
