The present invention relates to a tire for reducing rotation resistance to reduce rotation resistance and at the same time, maintain durability and appearance quality. To achieve this, according to the present invention, provided is a tire for reducing rotation resistance, which is a pneumatic tire, and comprises: a tread provided on an outer circumference to be in contact with a road surface; a carcass forming a frame of the tire; a side wall protecting the carcass and forming a side surface of the tire; and a bead coupled to a rim. The side wall is formed by bonding different types of rubber having different material properties. According to the present invention, rotation resistance performance is improved, and at the same time, after a curing process, the side wall is prevented from being cracked and appearance quality is improved.

    본 발명은 회전저항을 저감시킴과 동시에 내구성 및 외관품질을 유지하기 위한 회전저항 저감 타이어에 관한 것이다. 이를 위하여, 본 발명은, 외주에 구비되어 노면에 접촉하는 트레드, 타이어의 골격을 형성하는 카카스, 상기 카카스를 보호하며 타이어의 측면을 형성하는 사이드월, 림에 결합되는 비드를 포함하는 공기입 타이어에 있어서, 상기 사이드월은 물성이 다른 이종의 고무를 점착하여 이루어지는 것을 특징으로 하는 회전저항 저감 타이어를 제공한다. 따라서, 본 발명에 의하면, 회전저항 성능을 향상시킴과 동시에 가류공정 후 사이드월의 갈라짐을 방지하고 외관품질이 개선된 타이어를 제공할 수 있다.
