Lamps have the benefit of being both practical and beautiful. Of course, their main purpose is to light up a room. But some people don't want the boring cookie-cutter lamp that everyone else has. If that's you, then why not make an intricate tire lamp? You can make this design completely unique and personal to you, and you can even have the pleasure of knowing you crafted such a beauty.
Just remember that tires are pretty heavy, so you need to ensure that your ceiling has the capacity to hold such a weight. The last thing you want is your roof caving in.
