A while back someone had a problem getting their wheel off.  I think Tester said to put a couple lug nuts on but loose and drive the car a little to unfreeze the wheel from the axle.
 I was helping a friend this afternoon who had a flat in the parking ramp and sure enough the wheel wouldn’t budge.  Drove it back and forth a little and turned the wheel some and the thing popped loose.  I’d never experienced that before but saved a tow and a lot of frustration.  That’s the kind of thing that happens on a dark night on the side of the road.
