We are going to reinforce the bottom layer of tires by filling them with dirt, and we have a lot (probably the majority) that still have rims on them that should make it really sturdy. We're gonna use T-posts to reinforce it a little bit as well.
I'm excited, it won't be pretty but it's eco-friendly, and the tires will be USED for something! We didn't have the thousands of dollars it would cost to have them disposed of, so this is awesome!
