Take a small bottle jack and set it sideways against the hub. Hook a chain to the rims hand holes, across the top of the bottle jack and back to the opposite hand hole in the rim. Pump until it pops off.
I've seen folks make a little adapter to hold the chain on the bottle jack, but two people would make short work of this.
Don't heat the rims, that doesn't work very well and if the videos posted on youtube (also shared here at one point) are any guideline, the tires can blow with the added heat.
