The present invention provides a rubber composition that improves the dispersibility of silica in a rubber composition, reduces the viscosity of an unvulcanized rubber, and improves the heat build-up of a vulcanized rubber, and a tire using the rubber composition. SOLUTION: To 100 parts by mass of at least one rubber component selected from natural rubber and / or diene synthetic rubber, 85 to 200 parts by mass of silica, an imidazoline derivative, and the imidazoline derivative is an alkyl having 15 or less carbon atoms. A group or an alkenyl group, the alkyl group and the alkenyl group may be linear, branched, or cyclic, and are combined with at least one compound having a hydroxyalkyl group or a hydroxyalkyl group having an oxyalkylene unit A rubber composition characterized by comprising: [Selection figure] None |
