An elastomeric composition is provided, wherein the composition comprises an elastomer; a reinforcing filler comprising silica; an organosilane polysulfide; and a blocked mercaptosilane, wherein the weight ratio of the blocked mercaptosilane to the organosilane polysulfide is about 0.25:1 to about 5:1. The elastomeric composition may be utilized as a component of a pneumatic tire. Also provided is a method of producing an elastomeric composition, wherein the composition comprises an elastomer; a reinforcing filler comprising silica; an organosilane polysulfide; and a blocked mercaptosilane, wherein the weight ratio of the blocked mercaptosilane to the organosilane polysulfide is about 0.25:1 to about 5:1.
