What state are the wheels in when the car is driving?

When a car is driving, the wheels are usually in a rolling or sliding state. When the car accelerates, decelerates or maintains constant speed, the wheels will maintain a certain degree of contact with the ground, and the friction between the tires and the ground drives the car forward. At the same time, the wheels are also supported by the suspension system and braked by the braking system to ensure stable driving and safe braking of the car.
