when i was younger there was a guy at the service station that was doing a split rim and the damn thing exploded, ring took the top of his head clean off, killed him on the spot. Just last week at the shop one of the guys went out to put air in the tires of a wrecker that had just towed a car in, he checked the outside dually tire, no problem, went to check the inner tire and the minute he put air to it, it blew, had a ringing in his ear for two days.

if in doubt, KONG it!!!
