A tire-chain assembly for a vehicle-mounted wheel basically comprises annular inner and outer holders respectively engaging the inner and outer faces of the wheel. At least one traction chain crisscrosses over the road-engaging surface of the wheel between the two holders. The inner holder is provided with a flexible element that tightens the chain on the road-engaging surface. The outer end of the flexible element, which may be a chain, a rope or the like, is then secured to the holder on one of the surfaces of the wheel. There is provided a tightening mechanism so as to ensure self-locking of the tire-chain assembly on the wheel.
