TREAD RUBBER COMPOSITION WITH GOOD ABRASION RESISTANCE

摘要

PURPOSE: A tread rubber composition and a tire employing the tread made of the composition are provided, to improve the abrasion resistance, the brake power and the gasoline mileage. CONSTITUTION: The tread rubber composition comprises 40-90 parts by weight of a solution polymerization styrene-butadiene rubber containing 30-90% of vinyl component; 1-20 parts by weight of a nitrile-styrene-butadiene rubber containing 10% of acrylonitrile; and 9-40 parts by weight of a tin-coupled butadiene rubber.
