He claims that if you jack up one tractor wheel and run the engine so
the tachograph indicates 55 mph, the spinning wheel can turn 220 mph and
explode.


Did he mention how the 220 MPH was measured?

If you use a differential and keep one drive wheel from turning the other
drive wheel will spin twice as fast as the speedometer shows.

What was said above was, if you keep 3 drive wheels from spinning the last
wheel will spin 4 times faster than the speedometer shows.
