The present invention relates to a heavy load tire with a reinforced bead unit through a center steel chafer. The present invention relates to the heavy load tire having a structure where a carcass is turned up to surround a bead core, comprising the center steel chafer maintaining a predetermined distance from an inner surface of the carcass and provided inside the carcass. According to a configuration of the present invention, the present invention primarily blocks shear generated from the inside of the carcass by using the center steel chafer to reduce the shear of a terminal unit of the carcass generated by deformation such as load and reduces effects of strain to effectively reinforce a bead unit since the center steel chafer is not turned up around the bead core but formed in an intermediate portion of the inside of the carcass.

    본 발명은 센터 스틸 채퍼를 통해 비드부를 보강한 중하중용 타이어에 관한 것이다. 본 발명은 비드 코어를 카카스가 턴업하여 감싸는 구조의 중하중용 타이어에 있어서, 카카스의 내측에는 카카스의 내면과 일정간격을 유지하는 센터 스틸 채퍼가 구비된다. 본 발명의 구성에 의하면, 센터 스틸 채퍼에 의해 내측에서 오는 전단을 1차적으로 차단하여 하중과 같은 변형에 의해 발생되는 카카스 단말부의 전단을 감소시키며, 센터 스틸 채퍼가 비드 코어를 중심으로 턴업된 것이 아니라 카카스의 내부 중간에 형성된 구조이므로 스트레인의 영향을 줄여 비드부를 효과적으로 보강한다.
