The wheel center cap is an important part of the wheel as it covers the middle part of the wheel's outer face. The center cap is there to protect the wheel components from any moisture or damage that would make the wheel look flimsy.
Wheel center cap conceptThe wheel cap was designed to keep dirt and moisture out of the wheel bearing. During the early days, caps used on cartwheels and wagons evolved from wood to metal and plastic cap covers. Soon the caps started to range from small to larger caps to protect the wheel studs, nuts, and the bearings.
There are designs on caps that feature the logo of the vehicle manufacturer or model. The caps may come in different sizes but they do the job. They are exposed to a harsh environment which can cause physical damage to the center cap.
