A rubber composition for tire treads which comprises 100 parts by mass of a rubber component comprising 60-80 mass% natural rubber and 20-40 mass% modified conjugated-diene-based polymer having one or more kinds of functional group having atoms other than carbon and hydrogen atoms, 35-70 parts by mass of a filler, and 0.1-10 parts by mass of a glycerin/fatty acid ester composition, wherein the filler having a silica content of 3-30 mass%; and a tire which includes a tread formed from the rubber composition. The tire obtained using the rubber composition for tire treads has an excellent balance among rolling resistance reduction, wear resistance, tear resistance, and cut resistance. |
