How do tires spin?

Question

My partner has been asking me how tires spin (specifically on cars) and I don’t know how to answer. How do they spin without coming loose? How do they understand the speed you want them to go?

Thanks in advance!!

Wheels spin on bearings. Remember fidget spinners? The “spinny” parts of those are small wheel bearings, like for skateboard wheels.

It’s the same concept on a car, just bigger, and the shape of the bearings are a little different.
