The present invention relates to rubber compositions which have improved rolling resistance and improved grip on wet ground. These compositions are based on at least one elastomer matrix comprising at least one copolymer containing ethylene units and 1,3-diene units, wherein the molar fraction of ethylene units in the copolymer is within a range extending from more than 50% to 95%, the copolymer not containing any 1,3-diene units of formula CH2=CR-CH=CH2, the symbol R representing a hydrocarbon chain containing 3 to 20 carbon atoms; a liquid plasticizer comprising from 45% to 100%, by weight, of an unsaturated fatty acid triester of glycerol; more than 30 phr of reinforcing filler and a crosslinking system. The invention also relates to rubber articles comprising a composition according to the invention, in particular pneumatic or nonpneumatic tyres, the tread of which comprises a composition according to the invention.
