Abstract
A tire chain assembly includes a chain body having a first side provided with a first snapping member and a second snapping member detachably engaged with the first snapping member and a second side provided with a snapping hole and a rotation locking mechanism detachably locked on the snapping hole. The rotation locking mechanism includes a connecting plate, a snapping member, and a locking hook. Thus, the chain body is directly enclosed around the tire of a car without needing aid of a jack and without having to move the car, so that the tire chain assembly is mounted on the tire easily, thereby facilitating a user operating the tire chain assembly.
