Abstract: A traction system for the tire of a wheel of a motor vehicle for use in snow and ice conditions. A pair of diametrically opposed supports are positioned over the rim of the tire and radially extend over the outer side of the wheel. Traction cables are connected to the pair of opposed supports at the rim of the tire. A resilient bag member is positioned at the axial area of the outer side of the wheel and is connected to the pair of supports. The bag member can be inflated or deflated. When deflated, the bag member draws the pair of supports into a mutal tensile relationship and a mounted gripping relationship with the tire and the wheel. When inflated the bag member eliminates the mutual tensile relationship between the pair of supports and thus degrips the pair of supports from the wheel and the tire. One, two, or more pairs of supports can be connected to the bag member.
Abstract: A helical cable tire chain having a series of small multi-angular metal traction sleeves, a series of rubber rings, which are supported on a helical cable when it is attached to a tire so that the chain enhances the traction and gripping power on ice or snow.
