Abstract：The 355/50R22.5 wide-base and low-profile all-steel radial truck tire is mainly to open up the European market. After the completion of test demonstration and market testing in the later stage， it will be put into production in the European market with considerable economic benefits. The development and design of the 355/50R22.5 wide-base low-profile all-steel radial truck tire is mainly based on the preliminary design of the wide-base low-profile all-steel radial truck tire structure based on the European standard. According to different structural design schemes， the finite element analysis of the tire inflation profile and tire， the position of the shoulder and the bead force is determined by optimization to determine the final tire profile and frame material parameters. After the structural design is completed， the construction design of the tire developed in this project will be carried out. Finally， the finished product performance test of the tire mainly includes strength performance and durability performance test.

在目前的轮胎市场中，主要有斜交轮胎和子午线轮胎两种主要的结构类型，与斜交胎相比，子午线轮胎具有较好的操作稳定性、滚动阻力小、耐疲劳性能好以及高速性能好等一系列显著的优点，因此在许多应用领域，子午线轮胎都取得了非常明显的市场优势。因未来的市场限高限载的趋势，宽基低断面全钢载重子午线轮胎越来越成为市场主流。为满足市场需求，本论文设计开发的355/50R22.5宽基低断面全钢载重子午线轮胎，其带束层均采用钢丝帘线，主要用于载重及工程机械车辆上，在欧美国家市场销量较大。
