Abstract:
A rubber composition that can be used in applications such as automotive tires and can improve the fuel efficiency performance and driving stability of automobiles and the like, a method for producing a rubber composition, and a tire using the same are provided.A rubber composition comprising: (A) a conjugated diene rubber which is obtained by polymerizing a conjugated diene compound or polymerizing a conjugated diene compound and an aromatic vinyl compound and has a group having an active hydrogen and a group capable of chemically binding to a silica, (B) a silica, (C) a silane coupling agent (I) capable of reacting with a carbon-carbon double bond of the conjugated diene in the conjugated diene rubber, and (D) a silane coupling agent (II) capable of reacting with the group having an active hydrogen; a method for producing a rubber composition, which comprises mixing the above-mentioned composition; and a tire which is obtained by crosslinking and molding the rubber composition obtained by the method for production.
