PROBLEM TO BE SOLVED: To provide: a rubber composition for a tire that can improve high mileage, wet grip performance, abrasion resistance and rubber strength by excellent balance; and a pneumatic tire using the rubber composition.SOLUTION: A rubber composition for a tire includes: a rubber component including 10-80 mass% of an epoxidized natural rubber in which an epoxidation rate is 7-15% by mole based on 100 mass% of the rubber component; silica (1) in which a nitrogen adsorption specific surface area is at least 150 m/g; and silica (2) in which a nitrogen adsorption specific surface area is at most 100 m/g, wherein the total content of the silica (1) and the silica (2) is 30-120 pts.mass based on 100 pts.mass of the rubber component. |
