If you’re looking for a way to make use of any old tires you have laying around, then look no further. You can reuse your tires for a lot of different things. It’s actually one of the better ways to recycle old tires as well.
Recycled tire seat - Treated plywood, 2 inch foam, clear vinyl then covered with outdoor fabric. All stapled underneath. Screwed 3 little "legs" to bottom of plywood that sit down in the tire like a plug of sorts. This keeps the seat top in place.
