RE: Car wheel completely stuck on
Yep - jack up that corner gently knock the inner rim with a mallet, turn 90 degrees, hit, turn 90 degrees, so that the bond will finally break. You have to do the same method getting brake disks off when they have bonded to the hub.
Oh and when you get it off use some copperslip on your nuts and the contact surface of your alloy wheel so that this doesnt happen again!
If it has a face - Eat It.
