Abstract

Provided are a rubber composition having excellent wear resistance, a production method therefor, and a method by which the wear resistance of a rubber composition can be evaluated with high accuracy. The present invention is directed to a rubber composition in which a relationship between: a maximum value Ξ<c>of a correlation length Ξ<i>of 10 nm to 100 µm obtained by performing curve-fitting with specific expressions on a scattering intensity curve I(q) obtained by performing X-ray scattering measurement or neutron scattering measurement in a specific region; and a standard deviation σ<c>of the maximum value Ξ<c>is σ<c>≤ Ξ<c>/2, the rubber composition containing a rubber component having a glass transition temperature of not higher than -20°C.
