Did you know that just covering the wheel openings on a truck and trailer with a specially designed wheel cover can help save fuel? The wheel cover improves the overall aerodynamics of the vehicle which leads to less fuel consumption. This is especially true for highway applications with increased road speed.
In some fuel efficiency tests these wheel covers increased fuel savings by 2% when covers were on all eight wheels of the tractor trailer. Ryder® Fleet Products has aerodynamic wheel covers for steel and aluminum 22.5 x 8.25" standard wheels (generation 4).
The wheel covers are constructed from tarp fabric with stainless steel wire, are simple to install with no tools required, and the hub remains easily accessible through the center access door.
