The invention relates to a rubber composition which comprises an elastomer which is a copolymer of ethylene and of a 1,3-diene which comprises ethylene units which represent more than 50 mol % of the monomer units of the copolymer, the 1,3-diene being 1,3-butadiene or isoprene, 35 to 100 phr of a reinforcing filler which comprises a silica, a plasticizing system comprising a hydrocarbon plasticizing resin and a hydrocarbon liquid plasticizing agent, it being understood that the total content of hydrocarbon plasticizing resin and of hydrocarbon liquid plasticizing agent is greater than 10 phr and less than or equal to 80 phr. Such a composition confers on a tread of a tire an improved performance compromise between grip, roadholding and rolling resistance.
