With my 29" Airstreaks, and my wheel skis, I deal with this every spring and fall. Before I discovered the "round rod thru the bearing hole, and tap the rim half and it will fall right out" method, I used to haul my wheels to my crane yard. With some blocks on the tires on either side of the wheel, I would put it under a outrigger and slowly lower it, and it'd pop right out, kind of like they do it at a tire shop, but I didn't have to buy another piece of equipment.
