Abstract
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 specific polyfunctional acrylate; the contents of polyfunctional acrylate and of peroxide being such that the ratio of the peroxide content to the polyfunctional acrylate 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 polyfunctional acrylate content being greater than or equal to 1.25.
