Abstract
A tire chain for adding traction to a vehicle tire riding on snow and/or ice. The tire chain includes side members encircling the sides of the tires and cross members that extend across the tread from side member to side member. Securement devices secure the cross members to the side members. The securement devices include a hook shape defining an enclosure and an opening to the enclosure and a biasing member that spans the opening. The securement device is secured to one of the members and is snap locked onto the other member to enable manual removal of a selected one of the cross members for replacement.
