Summary: | PROBLEM TO BE SOLVED: To provide a rubber composition for a tire capable of improving fuel consumption property, wet grip performance and abrasion resistance in a good balance and further providing good workability, and to provide a pneumatic tire manufactured by using the rubber composition.SOLUTION: The invention relates to a rubber composition for a tire that contains a rubber component containing styrene butadiene rubber having the styrene amount of 20 mass% or more, silica and a styrene-butadiene block copolymer having a weight average molecular weight Mw of 4×10or more, and has the total content of the styrene butadiene rubber and butadiene rubber of 90 mass% or more in 100 mass% of the rubber component, the silica content of 5 to 200 pts.mass and the content of the styrene-butadiene block copolymer of 1 to 40 pts.mass based on 100 pts.mass of the rubber component. |
