The present invention has its object to provide a rubber composition having excellent low-exothermic property and high strength together, and a pneumatic tire produced using the rubber composition. The present invention relates to a rubber composition which contains a rubber component and 10 to 150 parts by mass of silica per 100 parts by mass of the rubber component. The rubber component contains a butadiene rubber modified by a compound represented by the formula (1):
wherein, R 1 , R 2 and R 3 are the same or different and independently represent an alkyl group, an alkoxy group, a silyloxy group, an acetal group, a carboxyl group, a mercapto group, or a derivative thereof; R 4 and R 5 are the same or different and independently represent a hydrogen atom or an alkyl group; and n represents an integer. |
