Wheel Covers – Trailer

Wheel Covers – Trailer

The aerodynamics associated with rotating tires and wheels are complicated by many factors. Wheel covers, which are inserted into the wheel of all tires, streamline the airflow around tires. They provide a net benefit to the fuel economy of the vehicle, but the improvement is small.

The cost, weight, and installation time of wheel covers is relatively small compared to other products. One set of four covers for a trailer complete with mounting bracketry may add 20 to 50 pounds to the trailer.

Multiple wheel cover designs are available. The primary design challenge has been making it possible to remove the wheel covers easily so that the wheels are accessible for inspection, maintenance, and repair.
