youll damage your face if you aint carefull lol, 'no im not joking':lol:
loosen the big centre nut, but dont remove it.
get a big bar 'socket extension bar is ideal' and give it a clout with a big hammer, that will break the taper and you will be able to just lift the wheel off.
prior to removal, note the exact position of wheel as it needs to go back in the same position.
sometimes you can just loosen the centre nut and give the wheel a sharp upwards tug and they come loose and thats why i say do not completely remove the nut (i once found out the hard way lol) i pulled the wheel off ok but smacked myself right in the kisser with it and split my lip open which ruined my stunning good looks for life:lol: :lol:
