Haven't fitted tyres for a long time, but when I did, I broke the beads by just pressing my heel, wearing stout boots, against the sidewall. Removed the tyre with levers. Fitting was made easier by smearing washing up liquid around the bead to lubricate the tyre, but only do that for tubeless tyres in case they creep. If the bead didn't seat straight away, then bouncing the tyre whilst using an airline was usually enough to make the tyre swell enough to seat properly. nowadays, my tyre supplier who carrys all the gear in his van, does it for free, including taking the wheels off, although that was for my CB1300. My wing is still in bits awaiting spares and powder coating!
