The invention discloses functional silanes containing non-active sulfur for silica sizing materials. A sulfur-vulcanizable rubber compound comprising a silane-functionalized diene elastomer, a silane coupling agent, and a silica filler. The silane coupling agent 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 sulfur-free silane coupling agent. The coupling agent comprises at least one terminal capping group that reacts with a hydroxyl group contained on the silica filler and a silane moiety contained on the diene-based elastomer.
