This invention relates to a rubber composition containing filler reinforcement comprised of precipitated silica with silica coupling agent therefore and conjugated diene-based elastomer which contains end-chain functionalization with multi-functional groups. The groups functionalizing the elastomer are multi-functional in the sense of containing one group reactive with at least one of said precipitated silica and silica coupling agent and another different group reactive with diene-based elastomers through sulfur cure of the rubber composition. A sulfur cured rubber composition containing said end-chain functionalization is provided. A tire is provided having a component comprised of said rubber composition. Representative of said tire component is a tire tread.
