PROBLEM TO BE SOLVED: To provide a silica-compounded rubber composition having higher modulus, being reduced in rolling resistance and being improved in vulcanization rate. SOLUTION: The rubber composition for tire comprises 100 pts.wt. of a diene rubber, 10-100 pts.wt. of silica and 1-30 pts.wt. of a lignonsulfonic acid salt or its modified form.
