Man, I’ve done that back in ’89 on my first 4x4. I went wheeling the night before a deployment ( short one, nothing fancy ). I had arranged to arrive at the air field by POV, and I got to parking area and I thought to myself - darn, that tire looks low. I checked and it was low and def. low pressure. I hustle inside, check in with 1sg and let him know I’m out with the truck, holler if I’m needed early, and assure him I’ll be locked up at attention for formation. bang, zoom, change the tire to the spare, hook up the flat tire in the spare location and hoof it back.
I return, do a visual on the tire thinking I picked up nail or something. Never occurred to me what happened. I took it to local tire place, they can’t find a nail or tire leak. after messing about for about half an hour, they unseat the tire and boom - there was a stick that was stuck in the bead. You couldn’t see it without unseating, it was sheared off, not sticking out of the tire. Only I could do something like this. or so I thought.
