Best way to break the rear tire bead is to place bike on center stand.
Take rear wheel off.
Put the side stand down ( I've welded a bigger foot on mine )
Place the rear tire under the side stand.
Rock the bike over on the center stand, using the side stand foot
to break the bead.
The front bead is usually easy to break with boot pressure.
It's a good idea to practice all this at home first.
