We have put a list of tire upcycling ideas for your inspiration. Sure, you'll find the good old tire swing here, but also some unexpected chairs, steps, dog bed, and garden decoration ideas.

Research indicates that tires will slowly leach toxic chemicals into the surrounding environment, but many of these studies describe long-term effects when exposed to the elements.
