This looks more like a classic case of the tire not being equalized all around the rim. If you have low spots in some places, you'll have high spots in others. The tire's bead is of a set circumference, if you move it inward to the hub, the circumference of the rim there is less so it'll be too long and want to bulge out elsewhere.

The thing you need to do is walk the tire away from the high spots toward the low spots. inflate the tire to about 5psi or just enough to fill it out and give it shape. Find the high areas, and push the tire in toward the rim there and push either or both sides in (not to the hub, but away from the rim) so you can slide it, and work it away from the high area to take up the slack. use the same method to push work tire toward the low area to give it the slack it needs so you can work it up the the correct position.

If you're struggling to overcome tire/rim friction, spray or dribble on some weak soap water solution as a lubricant.

If you have reason to pull the tube, compare it's width as I mentioned earlier. Wider tubes can make tire seating more difficult.
