Abstract
A rubber composition according to an embodiment contains a diene rubber and silica. A change rate of a distance between aggregates represented by V50/V0 calculated by an inertia radius V50 of a silica aggregate and an inertia radius V0 of the silica aggregate is 1.30 or more. The inertia radius V50 is obtained by performing a small-angle X-ray scattering measurement in a state where a vulcanized rubber obtained by vulcanizing the rubber composition is elongated by 50%, and the inertia radius V0 is obtained by performing a small-angle X-ray scattering measurement in a state where the vulcanized rubber is not elongated.
