The present invention relates to an ultra super single tire for heavy duty. The ultra super single tire for heavy duty of the invention includes a tread (110) that contacts the road surface; a carcass (120) that constitutes the skeleton of the tire; and a belt layer (130) that is disposed between the tread (110) and the carcass (120), in which the belt layer (130) is composed of a first belt to a fourth belt that are laminated sequentially from the carcass (120) toward the tread (110), the first belt (131) includes an extender belt (131b), and the second belt (132) is a wide spiral coil belt. The present invention exhibits effects of preventing an excessive increase in weight, the occurrence of excessive heat generation, and deterioration of durability, further enhancing the ground contact length at the ground contacting center, and further enhancing the durability at belt layer edges, by means of a wide spiral coil belt having a four-layer belt structure, in which the order of lamination of the helical coil has been changed and the width has been increased, and by means of an extender belt.
