The present invention discloses a tire for a heavy load in which a bead unit is reinforced. According to the present invention, in the tire for the heavy load where a carcass ply and a steel chafer turn up the bead unit, first and second reinforcing materials are interposed between the carcass ply and the steel chafer. In this case, a heat generated due to a tire's flexing/extending motion during driving is prevented from being accumulated, or a stress is prevented from being concentrated in the bead unit due to a repeated tensile and a compressive action. In addition, thermal separation caused by overloading, an over-air pressure, long-distance driving, and driving under adverse conditions can be prevented.

    본 발명은 비드부가 보강된 중하중용 타이어를 개시한다. 본 발명에 따르는 비드부가 보강된 중하중용 타이어는 카카스플라이와 스틸체파가 비드부를 턴업하는 중하중용 타이어에 있어서, 카카스플라이와 스틸체퍼와의 사이에 제1,2보강재를 개재시킨 것을 특징으로 하는데, 이에 의할 때 주행중 타이어의 굴신운동으로 인해 발생하는 열이 축적되거나 반복적인 인장 및 압축작용에 의해 비드부에 응력이 집중되는 것을 방지하고, 더불어 과적 및 과공기압, 장거리 주행, 악조건 운행 등으로 인한 발열 세퍼레이션(Separation)을 방지할 수 있다.
