An anti-skid tire chain is improved by having a resilient strap at one end, the strap being adapted to be secured on the inside wall of a mounted tire having its tread on a road surface. On both of the side wall links of the chain, there are plates having a plurality of sharply pointed hooks or barbs adapted to be pressed into the side walls of the tire when the chain is initially being secured to the tire. In order to have the barbs securely engage the tire so as to hold the chain thereon during the rotation of the wheel and tire, the resilient strap is extended transversely on the chain from adjacent one of the plates to the other and the plates are secured to the tire by pressing them against the side walls with the barbs extending toward the tire wall and toward the tread. At the same time the strap is stretched so that when it is released, the barbs will be additionally pulled into the tire by the resilient retraction of the strap. The barbs do not damage the tire but hold the chain thereon while the tire is rotated so that the opposite ends of the chain can be brought adjacent each other and secured together. The resilient strap has a hook on its free end which is used to engage the opposite end of the inside row of chain links and secures the chain tightly by the bias of the strap on the inside wall. A typical locking link is used on the outside wall to secure the outside row of links thereon.
