my $0.02, but I've frequently had this problem on my beat up Pontiac (read- "winter beater"). I have a f'ed up passenger side caliper bolt that likes to seize so the pads stay tight on the rotor causing lots of heat and frequent seized wheel. My practice is to jack the car up a bit and with the bottom of my shoe, while facing away from the vehcile I kick the ever lovin sh!t outta the bottom of the wheel. With a 22' wheel you should get some good leverage and your shoes wont damage the rim (if your anal, cover the rim with a towel, maybe secure it with tape). I feel this generates a ton of force and always works for me. Its kinda a hokey way of doing it and people might stare but its worked for me!!
But then again the picture probably showes why this usually works for me.
