Would it be possible to build a small 20' X 20' or 30' X 30' building using car tires using maybe one layer tires then black plastic to keep rain out then another layer of tires? If you just stack them vertical for the wall how would you build roof? Stacking them like great pyramids would look nice except I do not know how or if this would work with tires. By the way I can obtain a lot of tires. Draw me a detailed picture how to do.
