The invention discloses a low-flatness wide-base all-steel radial tire, which relates to the field of radial tires, and comprises a tire tread and four belt plies; the four belt plies comprise a firstbelt ply, a second belt ply, a third belt ply and a fourth belt ply; the outer contour of the tire axial section of the tire tread is formed by sequentially and smoothly connecting n sections of tread arcs, wherein n is larger than or equal to 6, the n sections of tread arcs are symmetrically distributed along the center point of the tread, the axial horizontal widths of the n sections of tread arcs are L1, L2, L3... Ln respectively, and the tread width of the tire tread is L. The tire is simple in structure; by optimizing the tread profile and the belt ply structure at the same time, the modulus of the belt ply rubber material is increased, meanwhile, the thickness ratio of the tread to the shoulder is controlled, so that the endpoint shear strain of the belt ply of the tire can be reduced, meanwhile, it is guaranteed that the grounding shape of the tire is uniform, the durability of the tire is improved, and the fault rate of the tire is reduced.

    本发明公开了一种低扁平宽基全钢子午线轮胎,涉及子午线轮胎领域,包括轮胎胎面和四层带束层,所述四层带束层包括第一带束层、第二带束层、第三带束层和第四带束层,所述轮胎胎面的轮胎轴向断面外轮廓由n段胎面弧依次平滑连接形成,所述n≥6,所述n段胎面弧分别沿胎面中心点对称分布,所述n段胎面弧的轴向水平宽度分别为L1、L2、L3…Ln,所述轮胎胎面的胎面宽为L,本发明结构简单,通过同时优化胎面轮廓及带束层结构,增加了带束层胶料的模量同时控制胎面与肩部厚度比,可以降低轮胎带束层端点剪应变,同时保证轮胎接地形状均匀,提升轮胎耐久性能,从而降低轮胎故障率。
