To provide a composition which comprises organosilicon compounds and can be added to a rubber composition to form a rubber composition capable of achieving desirable low fuel consumption performance and wear resistance performance while retaining the workability of the composition and the hardness and tensile properties of cured products thereof.SOLUTION: The composition comprises (A) an organosilicon compound represented by formula (1) and (B) an organosilicon compound having an alkoxysilyl group and one or more selected from a polysulfide group, a thioester group and a mercapto group. In the formula, R1 and R2 independently represent an alkyl group or an aryl group, R3 represents a hydrogen atom, an alkyl group, or an aryl group, R4 independently represents a hydrogen atom or a hydrocarbon group that may have a substituent other than a sulfur atom-containing group and may include a heteroatom other than a sulfur atom (adjacent R4 may crosslink with one another to form a ring), Z represents a divalent group not having a polysulfide group, thioester group or mercapto group, and n represents an integer of 1-3.SELECTED DRAWING: None
