What are the main functions of wheels?

The role of wheels is to support the entire weight of the vehicle and bear the load of the car. More details about wheels are as follows: Functions of wheels: Support the entire weight of the vehicle and bear the load; transmit traction and braking torque to ensure the adhesion between wheels and the road surface; reduce and absorb vibrations and impact forces during driving, prevent severe vibrations and premature damage to vehicle components, adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring driving safety, handling stability, comfort, and energy efficiency. Composition of wheels: Wheels are rotating components that bear the load between the tires and the axle, usually consisting of two main parts: the rim and the spokes. The rim is the part of the wheel that mounts and supports the tire, while the spokes are the supporting components between the axle and the rim. In addition to the above components, wheels sometimes also include the hub.
The main functions of wheels, in my opinion, are as essential as the feet of a car. Having driven for over a decade, I deeply understand that firstly, they support the entire weight of the vehicle—without them, the car would collapse and be immobile, unable to bear the engine, passengers, or any load. Secondly, wheels transmit driving force; once the engine starts, the rotation of the wheels propels the car forward or backward, relying on tire grip to prevent skidding on slippery roads. Thirdly, they enable steering—when turning the steering wheel, the wheels cooperate to navigate corners, crucial for agile handling. Fourthly, they absorb road shocks; at high speeds over bumps, tires cushion impacts to minimize body jolts, enhancing ride comfort. Fifthly, during braking, wheels generate friction to decelerate, ensuring a safe stop and preventing accidents. I always remind friends to check tire pressure and tread wear regularly, maintain wheel alignment, and prevent vibrations or increased fuel consumption. In short, if wheels malfunction, it’s like wearing unstable shoes—driving becomes hazardous and strenuous.
