We were trying to get the stock wheels off an SVT to get the summer wheels on, and they wouldn't come off either. We pounded on the stockies with a mallet as hard as we could without damaging anything, and soaked behind the wheel in WD-40. Then we got an idea of lowering the jack, just until the tire touched the pavement...it WORKED!! I guess it just needed 3,000lbs of pressure!

Failure is simply the opportunity to begin again, this time more intelligently.
