Abstract
Provided is a rubber composition that can achieve excellent on-ice performance and steering stability when used in tires. A rubber composition comprises: a rubber component containing an isoprene-based rubber, and a modified conjugated diene-based polymer that is a reaction product of a conjugated diene-based polymer having an active terminal and a compound [M] containing a total of two or more of at least one selected from a group “—CR1═N-A1” and a group “—N═CR1-A1”, where R1 is a hydrogen atom or a hydrocarbyl group and A1 is a monovalent group having an alkoxysilyl group; a filler containing at least silica; and 5 parts by mass or more of a thermoplastic resin with respect to 100 parts by mass of the rubber component.
