Gotta add my flat tire story in here. I had a slow leak, needed to top it up about every two weeks, came out one morning and it was totally flat. Drop the spare, but I could not get the lug nuts loose. Call AAA, they send out a dude, he changes the tire, all is well. Until I start driving, half an hour up the lake, and starting back down, at which point the wheel feels funny, so I pull over. All the lug nuts had gone away, and it was only the force of something nice in the world that the tire didn’t run away too. It was sitting on the lugs. Sorta.
