Abstract

56Provided are: a rubber composition which is capable of improving low fuel consumption and wet grip performance in a balanced manner; and a pneumatic tire which uses the rubber composition in tire constituent members (especially in a tread). The present invention relates to a rubber composition which contains: a rubber component that contains a copolymer which is obtained by copolymerizing 1 3 butadiene styrene and a compound represented by formula (I) said copolymer having an amino group at one end having a functional group containing at least one atom selected from the group consisting of nitrogen oxygen and silicon at the other end and having a weight average molecular weight of from 1.0 × 10 to 2.5 × 10; silica; and a diene rubber gel having a hydroxyl group and a glass transition temperature from 40°C to 10°C. The rubber composition contains 10 30 parts by mass of the diene rubber gel per 100 parts by mass of the rubber component.
