The invention relates to an elastomeric laminate and a tire comprising same, the elastomeric laminate comprising three adjacent layers called C1, C2 and C3 respectively: the C1 layer comprising a composition based on an elastomer matrix comprising mainly a copolymer containing ethylene units and 1,3-diene units, the ethylene units in the copolymer representing more than 50 mol% of the monomer units of the copolymer, a reinforcing filler, and a cross-linking system comprising at least one peroxide; the C2 layer comprising a composition based on an elastomer matrix comprising mainly a copolymer containing ethylene units and 1,3-diene units, the ethylene units in the copolymer representing more than 50 mol% of the monomer units of the copolymer, a reinforcing filler, and a vulcanization system; and the C3 layer comprising a composition based on an elastomer matrix comprising mainly a diene elastomer having a diene unit content by weight of more than 50%, a reinforcing filler, and a vulcanization system; the C2 layer being arranged between the C1 layer and the C3 layer.
