Abstract

본 발명은 NR(Natural rubber)계 고무층과 SBR(Stylene buthadiene rubber)계 고무층의 이중 고무층으로 트레드부를 형성시킨 자동차용 타이어를 제공하기 위한 것으로, 트레드를 SBR계 고무층(1)과 NR계 고무층(2)의 이중층으로 형성시켜 드레드 외측의 접지력 특히 코너링시의 접지력이 향상되어 조종안정성과 주행안정성을 향상시킬 수 있게 되었으며, 마모성능이 큰 SBR계 고무층(1)을 비교적 마모가 잘 되는 트레드 외측에 설치하므로서 트레드 전면의 마모도를 고르게 하여 편마모로 인한 단치가 발생되지 아니하게 하는 효과가 있는 것이다.The present invention is to provide a tire for an automobile in which a tread portion is formed of a double rubber layer of a natural rubber (NR) -based rubber layer and a stylene buthadiene rubber (SBR) -based rubber layer, and the tread is an SBR-based rubber layer (1) and an NR-based rubber layer (2). It is formed by double layer, so the traction of the outside of the thread, especially the traction in cornering is improved, so that the steering stability and driving stability can be improved, and the SBR-based rubber layer (1) having high abrasion performance is installed on the outside of the tread where it is relatively easy to wear. Therefore, the level of wear on the front of the tread is evenly applied, thereby preventing shortening caused by uneven wear.
