RUBBER COMPOSITION FOR TIRE

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition for tire tread improving cutting resistance chipping resistance and, keeping the high abrasion resistance of the tread rubber. SOLUTION: This rubber composition is obtained by compounding 2-10 pts.wt. of a phenolic compound-dicyclopentadiene copolymer resin in 100 pts.wt. of a rubber polymer component prepared by blending a natural rubber or an isoprene rubber with a high-cis butadiene rubber in the weight ratio of (50:50) to (90:10).
