I got a flat tyre on Sunday, first one in 20 years (then got one Monday in a different car), after removing the wheel nuts I was unable to get the wheel off the car. Luckily the local tilt tray operator stopped and coaxed it off with a gympie. Apparently it is pretty common for the alloy wheels to jam on the hubs. I think I will have to add a rubber mallet to the tool kit in the car.
