The invention relates to a rubber composition based on one or more specific functionalized diene elastomers and on one or more carbon blacks with a CTAB specific surface varying from 100 to 200 m2/g, the functionalized diene elastomer or elastomers being composed of a specific diene elastomer functionalized, at the chain end or in the middle of the chain, by a tin functional group and of a content of less than 15% by weight, with respect to the total weight of the functionalized diene elastomer, of a non-tin functional elastomer. The diene elastomer exhibits a monomodal distribution of molecular weights before functionalization and a polydispersity index before functionalization of less than or equal to 1.3. This composition makes it possible to obtain tires having an improved wear resistance and which are characterized by decrease in rolling resistance, without damaging the processing and the wet grip.
