Help : French wheel..

French people worry a lot about their "culture exception".
A good part of this is also related to smelty cheeses, cheese availability in United States...
What is a french wheel ?
It is a wheel that did not manage to escape to french tax administration !
More pragmatically...
Put the inflating hole of your wheel bottom side, and look it from above, the side that is not hidden by the tyre.
Then look at next picture.
First wheel is a french one,
Second wheel is NOT a french wheel.
