The invention discloses a coupling system for a rubber compound containing silicon dioxide. The sulfur-vulcanizable rubber compound comprises a silane-functionalized diene elastomer, a bis-silane coupling system, and a silica filler. The silane coupling agent containing non-active sulfur does not contain an active sulfur moiety. The rubber compound is a reaction product of a siloxy condensation reaction between a silane functionalized diene elastomer and a disilane coupling system. The dual coupling system comprises an inactive sulfur-containing silane coupling agent for reacting with associated precipitated silica to produce hydrophobic silica; and a cross-linking agent for reacting with a silane coupling agent containing non-active sulfur and related polymers.
