What worked best for me with a really troublesome wheel was this.

Went to home depot and bought a length of either 2X2 or 3X3 hardwood (a real good harwood is the key). I cut off a piece about a foot long and used that and my heavy hammer on the wings and I had it off in 5 minutes. I cut another foot-long piece and that stays in my toolbox in the trunk.
