A sulfur-vulcanizable rubber compound comprises a silane functionalized diene elastomer, a silane coupling agent, and a silica filler. The silane coupling agent excludes an active sulfur moiety. The rubber compound is a reaction product of a siloxyl condensation reaction between the silane functionalized diene elastomer and the non-sulfur containing silane coupling agent. The coupling agent comprises at least one end terminating group reactive with a hydroxyl group contained on the silica filler and a silane moiety contained on a diene-based elastomer.
