Ok, I can get all of the used tires that I want for free; some folks have offered me cash to take them too. I know that you can make shelters, etc. from earth filled tires...so I have been thinking about making a tornado shelter/root cellar out of earth filled tires. My question is...would this make a good tornado shelter as well as a root cellar? Also, what do you use to cover the 'inside' of the cellar with? I seen a earth filled tire shelter where they use chicken wire/mesh and cement to finish the inside of the shelter...but I was wondering if there was anything else that could be used?
