Over the decades, working always with hard aged tyres, I have always found it a battle. Whereas recent new tyres fell on like bicycle tyres.
Obviously the free bead and as much as possible of the bead being worked must lie in the bottom of the well. Once there and under tension will stay there but maintaining tension single handed is tricky. Several large G clamps or simillr can be applied to squeeze the tyre wall to wall and bring to beads closer together so dont keep rising out of the well..
Many advocate doing in the hot sunshine.
For years I used rubber grease but found it causes any patches to eventually lift. Sadly with obstinate tyres it is impossible to avoid paint damage to the rims. Sitting the wheel on a modern tyre lifts it off the floor and can be helpful. Avoid standing on the spokes.
Some years ago I visited a tyre firm and the fitter was grappling with an Austin type tyre. He seemd to be having even more difficulty than I experience.
Incidentally, in my late 70s, I still do tyre work on my "moderns" and always have. (I use an old VW jack against a concrete lintel to break beads free)
