Zusammenfassung:	The present invention relates to a use of a terminally modified liquid butadiene compound and, more specifically, to a tire rubber composition, a tire manufactured by using the same, and a manufacturing method of the tire, wherein the tire rubber composition comprises: a terminally modified liquid butadiene rubber compound synthesized by using a chain transfer agent having a triethoxysilyl functional group and a tetra sulfide functional group, and a 1,3-butadiene monomer; and a rubber polymer. According to the present invention, by introducing a silica-friendly functional group to both ends of the chain, fuel consumption characteristics can be improved, deterioration of physical properties according to a change over time can be prevented, and abrasion resistance can be improved by lowering a glass transition temperature of the liquid butadiene rubber. 본 발명은 양말단 변성 액상 부타디엔 화합물의 용도에 관한 것으로, 보다 상세하게는 트리에톡시실릴 작용기 및 테트라 설파이드 작용기를 가지는 사슬이동제와 1,3-부타디엔 모노머를 이용하여 합성한 양말단 변성 액상 부타디엔 고무 화합물; 및 고무 중합체;를 포함하는 타이어용 고무 조성물, 이를 이용하여 제조된 타이어 및 타이어 제조방법에 관한 것이다. 본 발명에 따라 실리카 친화형 관능기를 사슬 양말단에 도입함으로써, 연비 특성을 개선할 수 있고, 경시 변화에 따른 물성저하를 방지할 수 있으며, 액상 부타디엔 고무의 유리전이온도를 낮추어 내마모성을 향상시킬 수 있다.
