When a composition including(A) an organosilicon compound represented by formula 1 and(B) when an organosilicon compound having at least one group selected from a polysulfide group, a thioester group, and a mercapto group and having an alkoxysilyl group is added to a rubber composition, a rubber composition is imparted that can achieve low fuel consumption and wear resistance while the workability of the composition and the hardness and tensile properties of cured products thereof are maintained.(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, a thioester group, or a mercapto group, and n represents an integer of 1-3.)
