Beschreibung
Zusammenfassung:	A tire with improved wear resistance, rolling resistance and cohesion, comprises a rubber composition based on at least one elastomeric matrix comprising predominantly a random copolymer comprising ethylene units and conjugated diene units, the mole fraction of 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 specific zinc salt; in which composition the contents of zinc diacrylate derivative and of peroxide being such that the ratio of the peroxide content to the zinc diacrylate derivative content is greater than or equal to 0.08; said composition comprising from 5 to less than 65 phr of reinforcing filler; the ratio of the filler content to the zinc diacrylate derivative content being greater than or equal to 1.25.
