The present invention relates to a pneumatic tire and, more specifically, to a pneumatic tire with an improved structure of decoupling ribs to prevent abnormal wear of a shoulder section. According to an embodiment of the present invention, the pneumatic tire comprises: shoulder ribs formed in the circumferential direction of a tire shoulder section; decoupling ribs formed on outer portions of the shoulder ribs; and decoupling grooves for dividing the shoulder ribs and the decoupling ribs. The inner surfaces of the decoupling grooves extending from the shoulder ribs are formed to be recessed with a predetermined radius of curvature. The pneumatic tire further comprises a plurality of sipes extending from the decoupling grooves to communicate with the outside of the tire and are disposed side by side at predetermined distances in the circumferential direction of the tire.

    본 발명은 공기입 타이어에 관한 것으로, 보다 상세하게는 숄더부의 이상마모를 방지하기 위하여 디커플링 리브의 구조가 개선된 공기입 타이어에 관한 것이다. 본 발명의 일 실시예에 따른 공기입 타이어는, 타이어 숄더부의 원주방향을 따라 형성되는 숄더리브, 상기 숄더리브의 외측부에 형성되는 디커플링리브, 상기 숄더리브와 디커플링리브를 구획하는 디커플링그루브를 포함하는 공기입 타이어에 있어서, 상기 숄더리브에서 연장되는 디커플링그루브의 내측면은 소정의 곡률반경을 가지면서 인입 형성되고, 상기 디커플링그루브에서 타이어 외측을 향해 연통되도록 연장 형성되며, 타이어의 원주방향을 따라 소정거리 이격되어 나란히 배치되는 복수개의 사이프를 포함한다.
