The invention discloses a truck radial tubeless tire which comprises a tire body, the tire body comprises tire beads arranged on the two sides at intervals, and after the tire body is installed, the tire beads are combined on a rim; a tire body cord fabric layer is integrally formed between the tire beads, and the tire body cord fabric layer is arranged between the tire beads on the two sides in a circular ring structure after passing through the tire side part and the tire shoulder part of the tire from the tire beads to the tire crown part; the carcass ply reversely wraps the tire bead from the inner side to the outer side; the tire further comprises a steel wire reinforcing layer; the wrapping mode of the steel wire reinforcing layer is L-shaped wrapping; the steel wire reinforcing layer is composed of a plurality of steel wire cords arranged in parallel. According to the tire with the structure, under the action of the L-shaped wrapping mode of the steel wire reinforcing layer and the wrapping mode of the tire body cord fabric layer, the stretching deformation of the tire bead is effectively controlled, meanwhile, the inner cracks of the tire bead part in the using process of the truck meridian tubeless tire are reduced, and the service life of the truck meridian tubeless tire is prolonged. And the bearing performance of the tire bead part of the truck radial tubeless tire is reduced.

    本发明公开一种载重子午线无内胎式轮胎,包括轮胎,轮胎包括两侧间隔设置的胎圈,轮胎安装后,胎圈合着在轮辋上;胎圈之间一体成型有胎体帘布层,胎体帘布层从胎圈开始经过轮胎的胎侧部、胎肩部至胎冠部后,呈圆环状结构布设在两侧胎圈之间;胎体帘布层按照从内侧向外侧方式反包胎圈;轮胎还包括钢丝补强层;钢丝补强层的包裹方式为L形包裹;钢丝补强层由若干个钢丝帘线以平行排列的方式组成。通过上述结构的轮胎实现钢丝补强层的L型包裹方式与胎体帘布层的包裹方式作用下,不仅有效控制了胎圈伸张形变,同时,减少载重子午线无内胎式轮胎在使用过程胎圈部内裂口,而导致载重子午线无内胎式轮胎胎圈部承载性降低的缺陷。
