The marking gives the main dimensional specifications
of the wheel rim.
This marking may be:
- complete, for example 6 J 15 5 CH 36,
- simplified, for example 6 J 15.
There are 3 types of wheel rim edges (2) :
- those with two flat edges,
- those with two raised edges,
- those with one flat edge and one raised edge.
