Tire having a composition comprising an ethylene-rich elastomer, a peroxide and a specific acrylate derivative

A tire comprising a rubber composition based on:

• an elastomeric matrix comprising predominantly a random copolymer comprising ethylene units and conjugated diene units, the mole fraction of the ethylene units in the copolymer being within a range extending from 50% to 95%;
• at least one peroxide;
• and
• at least one acrylate derivative of formula (I)
• in which:
• R1, R2 and R3 independently of one another represent a hydrogen atom or a C1-C8 hydrocarbon group selected from linear, branched or cyclic alkyl groups, aralkyl groups, alkylaryl groups and aryl groups, and which are optionally interrupted by one or more heteroatoms, it being possible for R2 and R3 together to form a non-aromatic ring, and
• R4 represents a C1-C30 hydrocarbon group selected from linear, branched or cyclic alkyl groups, which are optionally interrupted and/or substituted by one or more heteroatoms.
