On a related note...
A friend of mine (call him B) had a neighbour (whom I'll call J), who was none too bright. B has been known to exploit this.
One day, J's car had a puncture, and he knocked on B's door to ask for help fixing it. B took a look, jacked up the car, removed the wheel, rotated it by 180o, and bolted it back on.
'You see,' he explained to J, 'the flat bit of the tyre was at the bottom where the tyre touches the road. It's now at the top, where it doesn't touch anything, so you won't have to worry about it any more.'
J thanked him.
But he was back the following day to ask for help again. Apparently the puncture had slid back to the bottom of the wheel overnight.
