Bob -
I wouldn't do that unless I have the car chokked and parking brake on. My
high school girlfriend knocked her '77 Firebird off the jack doing this very
same thing (the tire on the ground rolled the car backward when she turned
the wheel that was off the ground).
Thankfully she was fine. By the way.... she was (still is) tall, beautiful,
blonde and taught me how to drive a car (that very same Firebird) and to
surf... gotta love California.
