The present invention relates to a tread rubber composition for a tire, having improved braking force on a wet road surface while maintaining snow braking force in a hot region or winter. The tread rubber composition for a tire includes SBR with low temperature properties to maintain snow braking force, includes terpene resins to improve wet braking force, and includes a specific vulcanizing agent to compensate for wear/RR.
본 발명은 혹서 지역이나 겨울에 스노우 제동력을 유지하면서 젖은 노면에서의 제동력이 향상된 타이어용 트레드 고무 조성물에 관한 것이다. 상기 트레드는 스노우 제동력을 유지하기 위해 저온특성 SBR을 포함하고, Wet 제동력 향상을 위해 테르펜 수지가 포함되고 마모/RR 보완을 위해 특정 가류제를 포함하는 타이어용 트레드 고무 조성물이다.
