I always give my spare the old kick test when ever I am working around the back of the truck. That will also tell you if your tire is coming loose.
Years ago the Lady borrowed her Dad's truck to get some work done, including a trip up into the mountains to a cabin. She was lucky she didn't lose control when the spare came off and landed upright launching the back end skyward. Sure taught us to do a walk around and safety check on borrowed vehicles.
