ABSTRACT:
A stackable, non-skid snow chain ramp is disclosed for use in the installation of tire chains on both snowy and icy surfaces. The tire ramp is designed with a grooved top and bottom surface and is operated by laying a pair of the ramps in parallel, spaced the distance equal to the separation of the automobile wheels. Tire chains are then laid over the spaced ramps with the cross links of the chains inserted into spaced chain grooves. The tire is then driven up onto the ramp and brought to rest against a tire block and positioned within a wheel well constructed in the ramp. The chains are then wrapped around the tires and connected in a traditional manner. The bottom surface of the ramps contain a combination of grooves and replaceable spikes for use in both snow and icy surface conditions. The disclosed ramps are designed to permit symmetrical stacking for easy storage and conveyance.
