Driving carefully out of [XXX] here in Walker Minnesota using the newly opened east side of the parking lot exit and 50 feet later as I accelerated the Heavy Full size spare tire fell from under the rear of the truck and my 2002 Cadillac EXT left the ground as the tire bounced back up against the truck!!! If we had been going faster and in a Different area we may have been Killed! It's a terrible design to store a full size and very heavy spare tire.
