[0002] At present, most of the typical tubeless rims in use are designed according to industry standards. In the prior art, the rim portion of a typical rim is semicircular, and for a truck, the rim is prone to deformation when heavy load or poor road conditions occur, which leads to a transient decrease in tire air pressure and causes a traffic accident, and even a tragic accident of vehicle damage and death. Based on the above structural design, the prior art improves the structural strength of the rim by providing a steel bar on the rim, but this increases the complexity of the rim manufacturing process and affects the appearance of the product, and increases the difficulty of subsequent product surface treatment such as electrophoresis and paint spraying, which causes the rim to rust early. In summary, how to improve the structural strength of the rim while reducing the complexity of the rim manufacturing process has become a problem that needs to be solved by those skilled in the art.
