Hubcaps are important specimens of the wheels in a vehicle, they perform several functions both- functional as well as aesthetical. This is mainly meant to encase the middle part of the wheel, and as a result, covers up those pesky little lug nuts and also encapsulates all material required to mount a wheel onto your car proper, safely locking those bits behind moisture- dirt- and road grime-proof plastic. The technology behind hub caps is that they are made from materials like plastic, metal or aluminum and they are designed to push on tightly onto the wheel without further necessity of extra fastening hardware. There are different styles, each designed to match the look of the wheel and further enhances the vehicle's aesthetics. They are fitted to most passenger and light truck wheels as they are required to keep the visual aspects of the wheels outside under control.
