Abstract
This disclosure is to provide a rubber composition excellent in low loss property, breaking resistance and wear resistance. In order to achieve the aforementioned purpose, this disclosure is a rubber composition containing a rubber component having a diene-based polymer and a silica, wherein: the diene-based polymer has 3 or more modified functional groups capable of interacting with the silica merely within a range of ¼ of an entire chain length from a terminal, and has at least one monomer structural unit of a diene-based polymer among the modified functional groups; and a content of the silica is 60 to 250 parts by mass per 100 parts by mass of the rubber component.
