In accordance with the present invention, disclosed is a pneumatic tire for heavy duty with excellent durability. In accordance with the present invention, a radial tire for heavy duty with excellent durability includes a tread part, a side wall part, and a bead part, and, in regard to a tire for heavy duty including a belt part having first, second and third layers stacked from the inside of the tire between the tread part and a body ply, the radial tire is interposed between an upper part of a side wall rubber of the side wall part and a lower part of a wing strip rubber to improve adhesion between the side wall rubber and the wing strip rubber. Accordingly, since components are provided to make a reinforcement to mitigate a crack occurring between the side wall rubber and the wing strip rubber of the tire during driving, adhesion and fixture between the rubbers can be improved, thereby preventing a crack in spite of repetitive bending/stretching motions and driving.

    본 발명은 내구성이 우수한 중하중용 공기입 타이어를 개시한다. 본 발명에 따르는 내구성이 우수한 중하중용 래디얼 타이어는 트레드부, 사이드월부, 비드부를 구비하고, 상기 트레드부와 바디플라이와의 사이에 제1벨트층, 제2벨트층, 제3벨트층이 타이어 내부로부터 적층된 벨트부을 포함하는 중하중용 타이어에 있어서, 상기 사이드월부의 사이드월고무의 상부와 윙스트립고무의 하부에 개재되어 사이드월고무와 위스트립고무와의 점착력을 향상시키는 것을 특징으로 하는데, 이에 의하면, 주행중에 타이어의 윙스트립고무와 사이드월고무와의 사이에서 발생하는 갈라짐 불량을 개선하기 위하여 보강하는 구성을 구비하여 두 고무 사이의 점착력과 고정력을 향상시켜 반복적인 굴신 운동과 주행에도 갈라짐을 방지할 수 있다.
