The use of tire snow chains mainly includes two parts: installation and disassembly. First of all, it should be noted that the installation and disassembly process should ensure the safety of the surrounding environment and a large enough space environment to facilitate the spread of the chain; The chain is spread out in front of the vehicle, and then the entire locomotive is moved to the upper end of the snow chain. After it is completely stopped, the outer and inner buckles of the snow chain are fastened and tightened, and the moving vehicle continues to adjust the snow chain.
