Love this! I have seen the tires painted in creative ways to match the houses and/or gardens. Attach to the side of a barn, garage, house, or let stand in the garden. Grow flowers or herbs, or use as decorations.
I had a couple stem broken wine glasses. Use dollar store stemware or repurpose broken stemware. put glass down in plant and place a candle inside, use a citronella to keep bugs away or battery operated of children are around.
