JJ dont have anything to do with offset. It's how
the wheel is holding the tire to the rim. J is single
edge hump (outside bead lock) and JJ is double
edge hump (outside and inside bead lock). Offset
is measured by using this really simple method.
Lay the wheel with the outside down on a flat
surface, like a floor. Measure the total width
by using a straight piece across the wheel.
2:nd step is to measure from the rear side to
the mounting face of the wheel. Divide the total
width in half and subtract that half from the dimension
you get in the 2:nd step. The difference is the offset.

PS. Burt Reynolds was JJ in Cannonball Run.
