If the tire service is far and you have the time to make a special device for wheel flange, then see how it is done. With a simple device made of iron, it is enough to simply change the tire on the wheel. A homemade machine as a small copy of the factory allows you to manually work with wheels of different diameters.
The efforts of special mounting devices are quite large, so it’s better to fix a homemade tire mount firmly to the surface.
