Patent ID: 7174933

Claim:
A vehicle tire chain, for installation on a vehicle wheel resting on the ground, or roadway, comprising a generally circular, flexible side member on the inner face side of the tire, a generally circular, flexible side member on the outer face side of the tire, an attachment device provided on each side member to attach the ends for each to form a loop on the wheel, a multiplicity of flexible cross members between the two side members, arrayed on the tire tread in a repetitive pattern, and the pattern is of such density that there is always a cross member in the tire to ground contact area during operation, and the installation procedure includes the step of imposing adjacent cross members upon the edges of the tire to ground contact area, such that one or both of said adjacent cross members are deflected from their natural positions in the pattern, and said adjacent cross member or members deflected from their natural positions are slidably connected to the outer face side member and are extended through the sliding connection radially inward and beyond the side member a distance adequate to allow for the deflection during installation, and are adapted for tension means to be connected to the radially inward end of the extension.
