What happens if you put a wide tire on a narrow rim?

What happens if you put a wide tire on a narrow rim? If a tire that’s too wide for a rim is mounted, the tire shape becomes too tall and round, like a lollipop or lightbulb, and then it becomes floppy at the top because the casing is constricted. This can result in poor cornering performance and tire squirm.

What happens when a tire is too wide for the rim?
