Abstract

본 발명은 빙상제동성능을 향상시킨 자동차용타이어에 관한 것으로, 특히 트레드를 통상의 발포고무 조성물로 형성시키고 그 표면에 고경도 고무조성물을 피복하여서 된 것에 있어서, 표피층을 형성하는 고무조성물은 무게평균분자량이 200만 이상이고 표피층(2)의 트레드의 외측으로부터 10내지 30%를 점유하도록하여, 내마모성 및 조종안정성을 유지하면서 빙상제동성능이 우수한 타이어를 제공하는 것임.The present invention relates to an automobile tire having improved ice-breaking performance, and in particular, by forming a tread with a conventional foamed rubber composition and coating a hard rubber composition on its surface, the rubber composition forming the skin layer has a weight average. The molecular weight is more than 2 million and occupies 10 to 30% from the outer side of the tread of the skin layer 2, thereby providing a tire having excellent ice-breaking performance while maintaining wear resistance and steering stability.
