What does the J mean in rim size.

For example 17x7JJ or 17x7J.

What is the difference?

j is a term for a lip on the inside of the rim to stop the bead of the tyre running (or being pulled) off the rim (lets say under hard cornering double jj means theres a lip on boths sides of the rim ie left hand and right hand
