There is no way you will get the beads over any kind of lip on these rims because the rim is completely flat. Normal car/truck rims have a smaller diameter towards the center of the rim that allows for enough offset of the bead to get it over the lip.

As for taking these things off. MAN, I spent a long time last night taking about one on a duece rim I need for test fitting my 53's. That sucker has been rusted on the rim for many years!
Then I am having fun getting these rims to go IN the new tire! Talk about a TIGHT FIT!
