The present invention generally relates to a device for securing a tire to a vehicle so as to reduce the accidental or unauthorized removal of the tire from the vehicle. The device is particularly suitable for preventing the theft of a spare tire from a vehicle. More specifically, the device prevents an unauthorized user from gaining access to an opening in the vehicle which is used to lower and remove the spare. As a result, the device may save an individual hundreds of dollars and the annoyance of not having a spare tire when needed. The device is easily installed in many vehicles in around one minute.
