【Automobile Knowledge】Do you know the structure of car wheels? How to read the data?

1. Tire

This is the part of the car that is in direct contact with the ground. It is usually made of materials such as rubber and has complex patterns that can increase friction, ensure the vehicle's grip, and make driving safer, such as draining water on rainy days and gripping on sunny days.

2. Barrel

Commonly known as the wheel rim, it is a component that mounts and supports the tire. It cooperates with the tire to provide an accurate mounting position and support for the tire. It and the wheel hub together constitute an important part of the wheel, and are generally made of steel, aluminum alloy, and other materials.

3. Hub

It is the part where the axle is installed in the center of the wheel. It bears the weight of the vehicle body and is a very critical structure. It is usually made of metal and has high strength.

4. Spoke

The part that connects the wheel hub and the rim has various shapes. Its main function is to support the rim and tire, and to reasonably transmit various forces during vehicle driving.
