Abstract

The disclosure describes a traction device for mounting on a tire without having to remove the hub cap of a tire wheel on which the tire is mounted. The device comprises a plurality of radially extending arms which are pivotally connected at their inner ends to a common connector and a hook formed at the other end of each arm, the hook being shaped to embrace the tread surface and at least part of the side-walls of the tire. The hook is formed with a friction plate. The device is so constructed that when it is mounted on a tire, the common connector and the inner ends of the radial arms are spacedly and outwardly centrally aligned with respect to the hub of the tire wheel for easier mounting. Finally, the arms are tightened together so as to prevent slipping of the hooks over the tread surface when the tire rotates.
