Thanks Guys..
Just to be clear.. it is not the seating of the bead, once it is mounted, that I am having issues with. It is actually installing the tire on the rim without damaging the bead area... It seems the ones I have are just a tad undersized and are near impossible to get on the rim without bead damage.. Once on, they will seat up fine, but, of course, they leak at low pressures, because the bead is damaged.
