Help with tyre changes (heavy work!)

Do you know this, if you want to change the tires yourself and which sometimes just can’t be solved? I hate that. So the screws are already loosed, but the wheel stays on it on its own and can hardly be moved! I have always handled it so that I have used such spray and kicked it from the outside against the tire until it fell off. But that can’t be it, can it? Now to the actual question: Does someone have the same problem and tip as you make the more elegant ka Don’t think that’s so great for my car.
