Probably an insurmountable tolerance issue. There is a tool made by Bicycle research, specifically for pulling up poorly seated tires.
I suspect part of the problem is that the advent of hook sided rims has led to some loss of the standards involved. Straight side tires seated on the shoulders of Endrich pattern tims (like car and motorcycle tires). Tires made for hook edge rims seat based on the bead tucking under the hook, and so less effort is made to maintaining the size of the old seating location inside (radially) of the bead wire.
If you can't get these babies to seat properly, try other tires.
BTW- inflating to riding pressure and waiting a week so so, might relax the tire enough for a successful go at reseating.
