The invention relates to a functionalized elastomer blend for a tire tread. A rubber compound for a tire tread includes a maximum difference in styrene content between pairs of functionalized diene elastomers of greater than 30%. The at least one diene elastomer contains functional groups that can interact with precipitated silica also in the composition.
