Also, be sure to take advantage of the deep well in the centre of the rim.


Break the bead on one side, then break the bead on the other and push the tire sideways until one bead falls in to the well, then start leveraging the tire off the rim (or, at least as you start priying it up and over the edge of the rim allow the other side to fall into the well otherwise the bead will be very tight to pull over the lip.)

This is probably where modern motorcycle tire technique differs most from bicycles.
