Or my personal favorite
Get one (or two if one isn`t long enough) old ratchet strap put round the circumferance of the tyre and tighten enough too squash the tyre out and the bead onto the inner rim, with valve out and slippy stuff on tyre inflate with compressed air, job done
NOTE: be sure too have ratchet in the undo position before inflating! I found out too my cost once that the strap wil explode and whip you quite nicely if you forget too do so
