PROBLEM TO BE SOLVED: To provide a rubber vulcanization compound and rubber composition for a tire added improved filler fine particle dispersion by condensing with a filler in a rubber vulcanization compound, useful for improving fuel economy of a tire manufactured from the same and having reduced hysteresis.SOLUTION: There is provided a rubber composition for a tire containing 10 to 100 phr of (a) an aminosilane functionalized polymer selected from a group consisting of a conjugated diene monomer, a monovinyl aromatic monomer and a combination thereof, and manufactured by a method for manufacturing an aminosilane functionalized polymer including a process for polymerizing at least one kind of an anionic polymerizable monomer by initiating polymerization using a metal aminosilane compound, 90 to 0 phr of (b) at least one kind of a rubber polymer and 5 to 200 phr of (c) at least one kind of filler. |
