often disagree with Brucey, but the best and easiest way to get a tyre on is in my video..

edit....you need
just enough air in the tube....if you put too much air in, the tube may not fit in the tyre without pleats, which will chafe and puncture.
I don't think we are in disagreement. But for most tyres (pretty much everything except heavier puncture proof tyres with stiff beads) the toestraps either won't work very well (because the tyre is floppy) or they are not strictly necessary; once the second bead is mostly fitted and has tension in it, pinching the tyre causes the beads to settle in the rim well and they will only pop out again if the tyre is stiff (and wants badly to be another shape) and/or the beads lose their tension.
Only this morning I fitted a 'bad combination', a GP5000 to a carbon rim (which was fitted with a thick-ish rim tape in a shallow well) and it was tight enough, right enough, but it merely caused 'pink thumbs' rather than red thumbs or red face, red thumbs, blue language etc. I don't think toe straps would have been any great help with this or many other folding tyres; once a folding tyre is squashed against the rim by the toestrap, I don't see how you can be 100% certain that the bead is in the right place; to do that means moving the tyre and that usually means moving the toestrap.
FWIW I believe that the single thing that would best improve the chances of fitting many tyres would be a thing that keeps the second bead under tension, so that it doesn't pop out of the rim well. That way you could pinch the tyre to get the second bead in the well, and be reasonably sure it is going to stay there.
