The invention provides an all-steel truck radial tire with high tire bead durability, a tire bead sequentially comprises chafer, carcass ply, a rubber sheet, hard apex and soft apex from inside to outside along the radial direction of the tire, the height of the chafer in the vertical direction is HWC.I, the height of the rubber sheet in the vertical direction is HJP, the height of the rubber sheet in the vertical direction is HWC.I, and the height of the soft apex is HJP. The height of the hard apex in the vertical direction is HHBF, the height of a lower side plate of the outer contour of the tire is LSH, the width of the section of the tire is SW, the height of the section is SH, and the following relations are met: SH/SW is larger than or equal to 0.981 and smaller than or equal to 0.994, LSH/SH is larger than or equal to 0.520 and smaller than or equal to 0.558, HWC.I/LSH is larger than or equal to 0.581 and smaller than or equal to 0.605, and HHBH/LSH is larger than or equal to 0.575 and smaller than or equal to 0.638. The all-steel truck radial tire with high tire bead durability is realized by establishing a corresponding relation between the outer contour design of the tire bead part of the tire and the internal structure of the tire bead and optimizing the material of the tire bead.

    本发明提供一种具有高胎圈耐久性能的全钢载重子午线轮胎,所述胎圈沿轮胎径向由内向外依次包括:胎圈包布、胎体帘布、胶片、硬三角胶以及软三角胶,其中,胎圈包布在竖直方向的高度为HWC.I,胶片在竖直方向上的高度为HJP,硬三角胶在竖直方向上的高度为HHBF,轮胎外轮廓下侧板高度为LSH,轮胎的断面宽为SW,断面高为SH,满足如下关系0.981≤SH/SW≤0.994,0.520≤LSH/SH≤0.558,0.581≤HWC.I/LSH≤0.605,0.575≤HHBH/LSH≤0.638。本发明通过对轮胎胎圈部位的外轮廓设计和胎圈内部结构之间建立对应关系,以及对胎圈材质的优化,实现一种具有高胎圈耐久性能的全钢载重子午线轮胎。
