PROBLEM TO BE SOLVED: To obtain a rubber composition for a tire excellent in balance of electroconductivity, low heat build-up, and wet gripping properties without reducing the processability and the abrasion resistance. SOLUTION: This rubber composition for the tire obtained by formulating 20-100 pts.wt. carbon black with fixed silica having 70-300 m2/g specific surface area measured by nitrogen absorption, and 5-30 pts.wt. clay having 0.1-5.0μm average particle diameter, with 100 pts.wt. diene-based rubber.
