Agreed; your Metal Rim is seized to the Metal hub. Not unusual.
If possible; I understand it may be difficult, Jack up your car, keeping the
tire about 1-2" off the ground, loosen the bolts, and on your butt, with some good boots on, kick the rubber tire at 4 key points.
You get the point? You loosen the lug nuts, have free clearance and by kicking the tires at four key points, you can break it free.
Mine was seized and I did the same.
I did not have any tools or 2x4 or anything like that.
Finally, after some persuasion it broke itself free.
I guess everyone has their preferred way of dealing with this yes.
I did an inspection of the brake pads on the front wheels of my CLK a couple of days ago, and had no problem removing the wheels. Well, one was initially stuck, but it soon came away.
Today I moved on to do the rear wheels, and I cannot shift either of them. This can't be anything to do with handbrake on, or Park. Surely the wheel should just come away from the hub?
Does this need a good whack on the tire with a rubber mallet or a piece of 4x2 timber? What's the trick guys? - I would not want this to happen at the roadside.
