It aims at providing the rubber composition excellent in the low loss property, fracture characteristics, and abrasion resistance. In order to solve the above problems, the present invention is a rubber composition comprising a rubber component having a diene polymer and silica, wherein the diene polymer is in the range of 1/4 of the total chain length from the terminal. Only having three or more modified functional groups capable of interaction with the silica, having a monomer structure of a diene polymer between at least one modified functional group, and containing the silica The amount is 60 to 250 parts by mass with respect to 100 parts by mass of the rubber component. |
