This invention relates to a dicyclopentadiene (DCPD)-based resin functionalized with groups capable of reacting with silica or carbon black for use in high performance tires and a preferred method of preparing the functionalized resin comprising ruthenium-catalyzed ring-opening cross metathesis. The functionalized resin may comprise the reaction product obtained by contacting a polymer comprising units derived from (DCPD) and a vinyl monomer or vinylene monomer in the presence of a metathesis catalyst, wherein the vinyl monomer or vinylene monomer comprises at least one of the following functional groups: a silyl group, a siloxy group, or an alkoxysilyl group. This invention further relates to a tire tread composition comprising the functionalized resin and which exhibits enhanced durability, traction, handling, and extractability properties.
