Abstract: A tire chain installation ramp that may be easily assembled and disassembled without the use of tools. The tire chain installation ramp comprises a set of multiple lengthwise plates and a set of multiple crosswise plates. The lengthwise and crosswise plates are configured to interlock with each other to form a grid-style ramp suitable for supporting a tire off of the road surface as a tire chain is installed. After use, the lengthwise and crosswise plates may be disassembled, stacked face to face and conveniently stored in a space which is smaller in volume than the assembled ramp. An alternative embodiment is a tire chain installation kit comprising a ramp which can be assembled from lengthwise and crosswise plates as described above, plus a storage container. Another alternative embodiment is a method of installing or removing a tire chain. including providing a tire chain installation ramp or tire chain installation kit as described above.
