Abstract
An improved tire protection chain (14) is disclosed which comprises a plurality of flat metal rings (16) disposed in a staggered pattern over the tread surface of the tire. Means (18) are provided for joining the rings into a flexible mesh, this means comprising at least one flat, oblong chain link (20, 22) oriented so that one of its long sides (30) faces toward the tire surface and the other of its long sides (28) faces away from the tire surface. Attached to the side of the chain link which faces away from the tire surface is at least one traction stud (36, 38, 40). The central opening of the oblong chain link is configured so that rotation of the oblong chain link is limited relative to adjacent links or rings.
