Turn Old Tires into a Storage Bin via Curbly | DIY Design Community
The most original use for an old tire I have seen yet. This would be extremely simple to make as well. A flat lid with a handle, and some salvaged castors and your old tires have a new lease on life.
Author’s note: A very good cleaning and a couple coats of low VOC paint should make the tires safe for in home use. (I do not recommend bringing them inside without sealing them)
Author’s second note: If you are too scared to use these inside (And I understand completely) I am sure you have toys outside that could be rounded up with one or more of these.
