Abstract

PURPOSE: The titled composition with escellent wetskid characteristics, exothermic characteristics, etc., which comprises a styrene-butadiene copolymer rubber of a specified property, an amorphous 1,2-polybutadiene and a cis-1,4-polybutadiene in a specified weight ratio.
CONSTITUTION: The purpose rubber composition is obtained by compounding (A) a styrene-butadiene copolymer rubber containing 10W35wt% styrene, (B) an amorphous 1,2-polybutadiene having 60wt% or more 1,2-linkage and (C) a 1,4- polybutadiene having 80wt% or more cis-1,4 linkage, in a weight ratio of A+B/C of 25/75W75/25 and a weight ratio of A/B of 75/25W25/75. The composition has characteristics, which simultaneously satisfies requirements for slip resistance on a wet road, and low exothermic property during run, required for a tire to safely run a car.
