You can place it anywhere, however the wheels usually stay associated with the vehicle. Rarely, does a car thief change wheels and tires unless the car was stolen to be stripped. Secondly, car dealers usually are victim to theft's of wheels and tires - hence a traceable way to associate the wheels if law-enforcement comes across them during an investigation. --Thirdly, keep in mind that today 3M makes decals of VIN numbers that most car manufacturers are placing in many different places on the cars being produced today. If you have a fairly new BMW look around, you will see your VIN number plastered in several places, the most obvious is where the rear license plate goes. There are many you may not see as well. It's all about associating a VIN number with a particular vehicle in hopes of recovery if stolen.
