To provide: a new compound that greatly reduces hysteresis loss and largely improves abrasion resistance without accelerating scorch of rubber composition; a rubber composition using the compound; and a tire using the rubber composition.
The organosilicon compound contains: one or more nitrogen atoms and one or more sulfur atoms in a molecule; and one or more silicon-oxygen bonds. In the organosilicon compound, an electron withdrawing substituent is added to at least one of the nitrogen atoms or at least one of the nitrogen atoms forms an ammonium salt structure. The rubber composition is obtained by mixing a rubber component (A) composed of a natural rubber and/or a diene-based synthetic rubber with an inorganic filler (B) and the organosilicon compound (C). The tire uses the rubber composition.
