The invention relates to a tire provided with a tread, said tread comprising a rubber composition based on at least one diene elastomer, a zinc diacrylate derivative in the form of a zinc salt in which R1, R2 and R3 independently represent a hydrogen atom or a C1-C7 hydrocarbon group selected from linear, branched or cyclic alkyl groups, aralkyl groups, alkylaryl groups and aryl groups, which are optionally interrupted by one or more heteroatoms, R2 and R3 being able to form together a non-aromatic ring, and a peroxide. The contents of zinc diacrylate derivative and peroxide are such that the ratio of the peroxide content to the zinc diacrylate derivative content is less than or equal to 0.09, said composition comprising no reinforcing filler or comprising less than 50 phr thereof, the ratio of the filler content to the zinc diacrylate derivative content being less than or equal to 2.
