Use of an ethylene copolymer for making tire or tire tread compounds, wherein the ethylene-copolymer is a copolymer comprising units derived from ethylene and at least one alpha-olefin monomer having from 3 to 12 carbon atoms, preferably propylene and, optionally, having units derived from at least one non-conjugated diene, and wherein the ethylene copolymer is functionalized to have at least one functional group comprising at least one polar unit selected from a carboxylic acid group (or salts thereof), an anhydride group, an epoxy group, a glycidyl ether group or a combination thereof, and wherein the ethylene-copolymer comprises from 40 to 80 % wt. of units derived from ethylene, preferably from 44 % wt. to 76 % wt. of units derived from ethylene and at least 20% wt. of units derived from one or one alpha-olefin monomer having from 3 to 12 carbon atoms, preferably comprising at least 15% wt. of units derived from propylene. Also provided are compositions comprising the ethylene-copolymer and a conjugated diene polymer, method of making such compositions and articles containing them.
