Don't hurt your feet, use heavy boots. I had luck with a board and a BFH, using the board on one side of the wheel then the other then back. Didn't seem like it was moving at first but a couple hundrednN(dozen) hits later it was working its way loose. Forearms felt like Popeye! Lightly put anti-seize (not grease!) on the center bore of the hub - that's where it usually gets hung up. Son't use grease or even a lot of anti-seize as you do NOT want water carrying that slippery stuff creepy-like onto your braking surface!
I wouldn't kick a car, even if it were on jackstands, from underneath unless I also had a secondary support. Too easy to get a harmonic going and still knock the darned thing over. People die that way.
Another option is to, yes, HIRE IT DONE. Changing tires at a tire shop or gas station is CHEAP, they have the tools, and if they damage your wheel you get a new one. Go to a shop you trust (those of us who also love and drive OLD cars for kicks always know a decent mechanic... other than ourselves!)
