Abstract

An object of the present invention is to provide a rubber composition capable of producing a pneumatic tire with both excellent low rolling resistance and wet grip performance, and a pneumatic tire comprising the rubber composition. The rubber composition comprises: a diene-based rubber containing 10 mass % or greater of a modified diene polymer; and an aromatic modified terpene resin; wherein the modified diene polymer is a modified polymer obtained by modifying an unmodified diene polymer (A) with a nitrone compound (B) having a carboxy group; and a content of the aromatic modified terpene resin is from 0.1 to 50 parts by mass per 100 parts by mass of the diene-based rubber.
