The invention relates to the technical field of automobile tires, in particular to a tire apex design method and a tire apex structure, a first geometric parameter is the ratio of the linear distance from the upper end point of the vertical section of the apex to the lower end point of the vertical section of the apex to the vertical height from the widest position of the section of the tire to a bead heel; the second geometric parameter is the ratio of the sum of the maximum widths of the vertical section of the apex to the length of the vertical section of the apex after the vertical section of the apex is equally divided in the vertical direction; a finite element model is constructed for analysis, and durability data is obtained; optimizing the first geometric parameter and the second geometric parameter according to the durability data; parameter description is carried out on the shape of the apex by adopting the vertical section of the apex, finite element analysis is carried out, so that the width and height parameters of the apex are optimized, and the technical problems that in the prior art, an apex structure shape parameter standard is lacked, and an efficient and accurate reference effect is difficult to achieve in actual design are solved. And a design reference is provided for the durability of the tire.
