I was putting air in a handtruck tire when I noticed the tread start to make a funny noise just a few inches from my head. I started to move my body away just as it exploded. But I'm pretty sure I kept the air chuck on the valve stem. Professional Grade.
I had put new-to-me tires and wheels on my 76 CJ7. Replaced those lame steel wheels with some sweet aluminum bullet hole wheels. Of course I was 16 and didn't know that steel wheels use different lug seating profile than steel wheels. I had maybe 100 miles on it. I had been going down interstate 85 southbound from Charlotte, headed to meet family for dinner. I pulled off interstate 85 at exit 24 in Lowell, NC, pulled into the Hillbilly's BBQ parking lot, and as I started turning into the parking space, I felt the right front drop and watched my wheel and tire disappear over the hill, across the southbound on ramp, across the grass, and stop inches from the white line of the travel lane.
I was working on my TJ in my parents driveway, don't remember the reason. But it was on 4 jackstands with the tires off, like usual (see avatar, too much irony right now!). Their driveway slopes down to the parking area. My buddy Zach came over in his YJ. parked just up the hill, and saw a toad as he was pulling out (you can't make this stuff up, he's a "snake guy" and likes to catch toads to feed to the snakes). So he jumps out, gets the toad, comes over to the jeep and talks for a minute. I'm still not sure what I was working on, but whatever it was, I was laying under the jeep with a battery charger. We talk another minute as I crawl out from under the jeep, then go in the garage. About the time we get inside, we hear a bang, followed by another bang. Apparently his YJ had come out of gear, rolled into my TJ, deflected, and slammed into the adjacent carport pole. Upon hitting my TJ, it got knocked off the jackstands, warped a jackstand, and crushed dad's battery charger, which was right where I had been laying. At the time, since nothing on the jeep was broken, I was just pissed about the battery charger. In hindsight, the battery charger didn't matter so much.
