Provided is a rubber composition for tires. From 35 parts by mass to 60 parts by mass of carbon black having a CTAB adsorption specific surface area of less than 70 m2/g and from 3 parts by mass to 30 parts by mass of silica having a CTAB adsorption specific surface area of less than 180 m2/g are blended per 100 parts by mass of a rubber component containing 50 mass % or more of natural rubber and from 10 mass % to 40 mass % of butadiene rubber. The butadiene rubber uses an unmodified butadiene rubber having a cis-1,4 bond content of 97% or more, a Mooney viscosity ML1+4 at 100° C. of 45 or more, and a ratio Tcp/ML1+4 of a 5 mass % toluene solution viscosity Tcp (unit: cps) at 25° C. to the Mooney viscosity ML1+4 ranging from 2.0 to 3.0.
