Lefty tighty. Get it righty.
If the problem is pushing the bead off the rim initially, tyre levers don’t help as you can’t get them under the bead. I struggle myself with this on tubeless tyres, two options stand on the tyre and pull up on the spokes which rarely works for me or get a piece of wood but it against the edge of the rim and give it a whack. That always works.
I've got a tyre lever with a very pointy end ( came with some tubeless stuff I bought) that is specifically for getting a well seated tubeless tyre off the rim.
