US 2016/0355057 A1 · RUBBER COMPOSITION AND PNEUMATIC TIRE

Abstract

An object of the present invention is to provide a rubber composition capable of producing a pneumatic tire with both satisfactory heat build-up reduction and excellent wet skid performance, and a pneumatic tire comprising the rubber composition. The rubber composition of the present invention contains a diene-based rubber containing from 5 to 40 mass % of a modified butadiene rubber and a white filler. The modified butadiene rubber is a modified polymer obtained by modifying an unmodified butadiene rubber (A) with a nitrone compound (B) having a carboxy group.
