Abstract

Provided is a rubber composition capable of preventing discoloration due to an amine-based antiaging agent and wax without deteriorating the ozone resistance not only in cases where the rubber composition is used in side wall portions of tires but also in cases where the rubber composition is used in tread portions of tires. The rubber composition comprises at least one rubber component selected from a dienic synthetic rubber and a natural rubber and, as incorporated therein, at least one nonionic surfactant selected from specific compounds.
