<p>PROBLEM TO BE SOLVED: To provide a rubber composition in which the dispersibility of an inorganic filler into the rubber composition is improved, the viscosity of an unvulcanized rubber is reduced, and the low heat generation property of a vulcanized rubber can be maintained, to provide a tire using the same, as well as to provide an unvulcanized rubber viscosity reduction method.SOLUTION: The rubber composition is characterized, and obtained by blending an inorganic filler and at least one of compounds represented by the following formula (I) into at least one rubber component selected from natural rubber and/or diene-type synthetic rubber. In the formula (I), each of Rand Ris an alkyl or alkenyl group having 1 to 24 carbon atoms, the alkyl and alkenyl groups may be any of straight chain type, branched chain type and cyclic type, each of Rand Ris an alkylene group having 2 to 5 carbon atoms, and each of n and m is a number of 1 to 5.</p> |
