The present disclosure is directed to tire rubber compositions containing at least one rubbery polymer (with 10 to 100 weight percent of monomer units derived from conjugated diene monomer having between 4 and 8 carbon atoms and 0 to 90 weight percent of monomer units derived from vinyl aromatic monomer); 0.5 to 100 phr of silica filler; 0.05 to 20 phr of a bi-functional silica coupling agent; and 1 to 30 phr of a non-elastomer reactive filler reinforcing agent capable of interacting with at least two silica particles. The bi-functional silica coupling agent and the filler reinforcing agent are utilized in a weight ratio of from 1:100 to 1:0.2. Also disclosed are methods for preparing the tire rubber compositions.
