A hubcap is a cover that fits over the central part of a vehicle's wheel, also known as the hub. It is designed to protect the hub from dirt, debris, and moisture, while also improving the appearance of the wheel. Hubcaps are typically made of metal or plastic and can be decorative or functional. They may also help keep the wheel securely attached to the vehicle by covering the bolts or fasteners. In some vehicles, hubcaps are designed to be easily removed and replaced for maintenance or styling purposes.
