AI Technical Summary
Conventional vehicle tire chain installation methods are cumbersome and time-consuming, especially in adverse weather conditions and challenging terrains like downhill and uphill roads, making them difficult for many users, including women and young people.
A split-type metal-nonmetal tire chain is installed on the upper surface of the tire wheel, with straps, ropes, and wires passed through the tire-wheel space and secured by a holding mechanism.
The tire chain can be quickly attached and detached under any conditions, facilitating easy use by a broader range of users.
