<p>PROBLEM TO BE SOLVED: To provide a rubber composition for a tire which enables high fuel economy and wet performance to be largely increased by improving interaction between a rubber and a filler.SOLUTION: The rubber composition for a tire is used which contains 5-150 pts.mass of a filler based on 100 pts.mass of a modified diene-based rubber component that has an end group represented by the following formula (B) in at least one molecular terminal, and that includes 0.01-5 mole% of an alkoxysilyl group. In the formula (B), Rdenotes a C1-10 alkyl group, Rdenotes an alkyl group, an aldehyde group or a carbonyl group, Rdenotes a C1-10 alkyl group, m is a number of 1-3, n is a number of 1 or 2, l is a number of 0-2, and the sum of m, n and l is 4.</p> |
