The present invention relates to a wide tire for heavy duty. The wide tire for heavy duty of the present invention comprises: a tread grounded on a road surface; a carcass composing a structure of a tire; and a belt layer arranged between the tread and the carcass, wherein the belt layer is composed of a first belt to a fourth belt sequentially laminated from the carcass to the tread. The first belt includes an amplification belt, and the second belt is composed of a wide spiral coil belt. The present invention changes a laminating order of the spiral coil in a four-layer belt structure and uses the wide spiral coil belt with a wider width and the amplification belt so as to prevent the tire from having an excessively increasing weight, excessively generating heat, and being degraded in durability. In addition, a grounding length of a grounding central portion is more increased and durability of a terminal end of the belt layer is more improved.

    본 발명은 중하중용 광폭타이어에 관한 것이다. 본 발명의 중하중용 광폭타이어는 노면에 접지하는 트레드; 타이어의 골격을 이루는 카카스; 트레드와 카카스의 사이에 배치되는 벨트층;으로 포함하며, 벨트층은 카카스에서 트레드 쪽으로 순차적으로 적층되는 제1벨트 내지 제4벨트로 이루어지고, 제1벨트는 증폭벨트를 포함하며, 제2벨트는 광폭 나선형코일 벨트로 되어 있다. 본 발명은 4층 벨트구조로 하면서 나선형 코일의 적층순서를 변경하고 폭을 증대시킨 광폭 나선형코일 벨트 및 증폭벨트를 통해, 중량이 과도하게 증가하는 것, 과도한 발열이 발생하는 것 및 내구성이 저하되는 것이 방지되며, 접지 중앙부의 접지 길이를 더욱 증대시키고 벨트층 끝단의 내구성을 더욱 향상시키는 효과가 있다.
