The present invention provides a rubber composition for tires having improved fuel efficiency, wet grip performance and wear resistance in a well-balanced manner, and a pneumatic tire produced using the rubber composition. [Solution] The styrene butadiene rubber, butadiene rubber and silica are included, and the content of the styrene butadiene rubber in 100% by mass of the rubber component is 40% by mass or more, the content of the butadiene rubber is 20% by mass or more, and 100 parts by mass of the rubber component. The tire rubber composition having a silica content of 50 parts by mass or more, the styrene butadiene rubber having an average molecular weight of 800,000 or less and an average vinyl content of 40% by mass or more.
