Provided is a rubber composition for tire treads that is capable of producing tire treads for which abrasion resistance, rolling resistance, factory workability, and chipping resistance have been simultaneously improved, and a pneumatic tire manufactured using the same. The rubber composition according to the present invention includes 20 parts by mass to 100 parts by mass of carbon black combined with 100 parts by mass of a rubber component. The carbon black has a CTAB surface area of 60 m2/g to 105 m2/g, a 24M4DBP oil absorption of 70 cm3/100 g to 105 cm3/100 g, a N2SA/IA of 0.95 or less, and satisfies Expression (1). TINT (%)+0.4×24M4DBP oil absorption (cm3/100 g)-0.5×CTAB surface area (m2/g)>106 (1) |
