See this extra hole? It is the CTIS hole that allows the hummer wheels to be remotely inflated. Not used in this application, but if you're static balancing instead of bead balancing make sure that you line up the CTIS holes on the two wheel halves. It is a good point of reference to make sure that you keep the two wheel halves clocked the same in relation to each other when you take them apart.
