On an older car (+10 years) you could never cleanly remove the pinch bolt without destroying it, the worst I've ever had was a 10ton press at maximum and a blowtorch to remove the bolt, and it gave way with one hell of a bang. If you have a car with pinch bolt setup then your best off removing the bolt every year or two and sticking a bit of copper slip on and refitting, only takes a couple of minutes and you don't need to take the wheel off.
