Abstract

본 발명은 트레드부가 기존의 부타디엔 고무와 천연고무 혼합물로 이루어지되, 주로 천연고무의 비율에 따라 3중 구조로 구성되고, 동시에 블럭이 다소 작고 조밀하게 설계된 트레드 패턴을 가짐으로써 겨울용 트레드로서의 특성과 빙상, 설상에서의 제동력 및 구동력의 향상이 기대되는 겨울용 스터드레스 타이어에 관한 것이다.In the present invention, the tread part is composed of a conventional butadiene rubber and natural rubber mixture, mainly composed of a triple structure according to the ratio of the natural rubber, at the same time the block has a rather small and densely designed tread pattern as a winter tread and ice sheet The present invention relates to a winter studless tire which is expected to improve braking force and driving force on snow.
