A rubber composition is based on at least one diene elastomer with a glass transition temperature (Tg) of less than −40° C., one reinforcing filler at a content from 60 to 110 parts by weight per hundred parts by weight of elastomer (phr), one vulcanization system and one combination of plasticizers, the said combination of plasticizers comprising more than 10 phr of at least one hydrocarbon resin with a glass transition temperature (Tg) of between −40° C. and 20° C. and at least one supplementary plasticizer selected from plasticizing oils, hydrocarbon resins with a Tg of greater than 20° C. and their mixtures, the total content of plasticizer being within a range extending from 25 to 65 phr, the contents of reinforcing filler and of plasticizer being such that the ratio of the total content of filler to the total content of plasticizer is within a range extending from 1.8 to 2.5.
