The invention belongs to the technical field of tires, and relates to a tread formula, a tread structure and a manufacturing method thereof.The tread structure comprises a middle tread arranged in the middle of a tread, a first tread and a second tread, the first tread and the second tread are arranged on the two sides of the middle tread, and the width ratio of the first tread to the middle tread to the width ratio of the second tread to the middle tread ranges from 1: 4 to 4: 1; the invention also provides a formula composition of the first tread, the second tread and the middle tread, and provides a manufacturing method for forming the multi-composite tread structure. The invention provides a multi-composite tread structure using multiple tread formulas, and the selected combination modes of the rubber formula of the tread are multiple, so that specific performance can be provided for a tire; sizing materials with different properties can be selected for the tread of the tire to solve the problems of premature cracking, irregular abrasion, nail disengaging and the like in a targeted manner, and meanwhile, the ice and snow performance, the rolling resistance and the like can be improved; the manufacturing method provided by the invention is a simple multi-composite tread composition method, equipment investment is not increased, the production cost is reduced, and the manufacturing method is suitable for implementation production.

    本发明属于轮胎技术领域,涉及一种胎面配方、胎面结构及其制作方法,胎面结构包括设置于胎面中间位置的中部胎面以及设置于中部胎面两侧的第一胎面和第二胎面,第一胎面和第二胎面与中部胎面的宽度比为1:4~4:1,并提供了第一、第二、中部胎面的配方组成,提供制作方法组成多复合的胎面结构。本发明提供了一种使用多种胎面配方的多复合的胎面结构,胎面的胶料配方选取组合方式多,可提供给轮胎特定的性能;而其胎面可选用不同性能的胶料来有针对的解决过早开裂、不规则磨损、脱钉等问题,同时还能够提升冰雪性能及滚动阻力等;本发明提供的制作方法是一种简单的多复合胎面组成方法,可不增加设备投入,降低生产成本,适用于实现性生产。
