Before you jump to conclusions, I've had two friends lose wheels while going down the road. For real...one in a truck that looked like a monster truck. His tire took out a shed! Neither of them thought they could have possibly left something loose. I've started to back out of the driveway and remembered--oh yeah I need to tighten those. It's ok...I bet you'll put a little more muscle on 'em next time.

Make sure and check your lugs. They could be damaged from the vibration.
