RUBBER COMPOSITION FOR TIRE

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition for a tire, capable of reducing rolling resistance and improving grip performance compared to the conventional levels. SOLUTION: The rubber composition is characterized by compounding 10-120 pts.wt. silica having BET specific surface area of 70-300 m2/g based on 100 pts.wt. diene rubber containing≥10 wt.% of styrene-butadiene rubber whose main chain is modified with a carboxyl group.
