The present invention relates to a snow chain for vehicle wheels, whereby the snow chain comprises two chain members adapted to extend along the peripheral tread surface of the vehicle wheel when the snow chain is mounted on said wheel. The snow chain comprises tie bars connecting the chain members to each other and adapted to extend transversely to the tread surface when the snow chain is mounted on the vehicle wheel. The snow chain preferably is mounted on arms which are foldable relative to each other and retractable to a position adjacent an end side of the vehicle wheel by means of a retraction device. In order to improve the grip between the snow chain and a ground (road), each tie bar is non-rotatably connected to the two chain members extending along the peripheral tread surface of the vehicle wheel in order to utilize the chain members for preventing the tie bars from turning or rotating from predetermined, preferably upright or standing positions relative to the tread surface when the tie bars, during rolling of the vehicle wheel, are positioned between the tread surface and the ground. |
