Designed by pilots who know a lot about aerodynamics, these light-weight aerodynamic wheel covers fit neatly on any 22-1/2 steel or aluminum rim in minutes? A very simple tube-ring holds the disc snugly on the wheel without special tools. Our new patent-pending J-Clip adheres to the wheel in seconds to hold the tube-ring firmly in place on both steel and alloy wheels. Best of all, independent studies have shown that when AeroTech Caps aerodynamic wheel covers are installed on the rear tractor and trailer wheels, average MPG is improved by as much as 2.44%. If your company has numerous trucks on the road, that could add up to huge savings very fast.
