rims stuck on car

Help!!!!
Need to replace tires and all four rims will not come off of car. Was told rust might be problem. Anyone heard of this and what is solution.

Put one bolt back on to hold the wheel on (so it doesn't fly off) and then take a rubber mallet and give the wheel a good whack from the inside - this will usually do it.

I wouldn't care if the tire flew off but he's got the right idea, beat the hell out of it with a rubber mallot or 2x4 or something that won't damage it and whack away. or it would be kind of funny to remove all bolts and then drive it, those bastards wont stay on long:lol: :lol:

some good pennatrating oil then take a 12lb sledge hammer to it
