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

A tire comprising a rubber composition based on at least:

• 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%;
• a peroxide;
• and
• a zinc diacrylate derivative in the form of a zinc salt of formula (I)
• in which R1, R2 and R3 represent independently of one another a hydrogen atom or a C1-C7 hydrocarbon-based group selected from linear, branched or cyclic alkyl groups, aralkyl groups, alkylaryl groups and aryl groups, and optionally interrupted by one or more heteroatoms, R2 and R3 possibly together forming a non-aromatic ring,
• wherein contents of zinc diacrylate derivative and of peroxide are such that a ratio of peroxide content to zinc diacrylate derivative content is greater than or equal to 0.08,
• wherein the composition comprises from 5 to less than 65 parts by weight per hundred parts by weight of elastomer, phr, of reinforcing filler, and
• wherein a ratio of filler content to the content of zinc diacrylate derivative is greater than or equal to 1.25.
