I'll break one down and see. I feel like all of the rims split on the outer edge of the rim. The ridge that your seeing in the photo's look like just a recess to allow the tire to slip into.
I'll see if I can beat one apart today. I was hoping to not restore the wheels until I restore the truck, but I know I will not be able to have the tires off and not clean up the wheels and paint them!
