ELI5: When a car wheel rotates, does the air in the tyre also rotate?

Does the air in the tyre rotate along at the same speed as the wheel, or is it stationary, or is there some kind of turbulence inside the tyre?

A good analogy would be stirring a cup of tea. The tea moves, but not at the same speed as the teaspoon.

It would be the same for the air in a tyre. Like the tea, air is a type of fluid - so the friction between the rubber and the air will cause the air to rotate, but not at the same speed as the tyre.
