AeroTech Cap
The tire wheel cover proven to cut fuel consumption of Class 8 trucks by as much as 1%. With AeoTech Cap installed on trailers, the combination saves up to 2.5%.

“Complexity is your enemy. Any fool can make something complicated. It is hard to make something simple.” -Sir Richard Branson

Save Fuel and Increase Profits

Designed by pilots who know aerodynamics, these light-weight dimpled discs fit neatly on any 22-1/2” steel or aluminum rim in minutes – including super-singles! Engineered to incorporate the same technology adopted by golf ball manufactures to improve aerodynamics and make the ball go further with less resistance. A very simple O-ring and spring assembly allows our discs to easily attach to any wheel system without special tools. Best of all, independent studies have shown that when AeroTech Caps are installed on the rear tractor and trailer wheels, average MPG is improved by as much as 2.44%.* That may not sound like a lot, but studies indicate that our aerodynamic wheel covers could save the average truck driver $1,500 or more each year. If your company has numerous trucks on the road, that could add up to huge savings very fast.

Rigorous Testing

During the research, development and testing process for AeroTech Caps, an independent company conducted testing to identify the fuel savings that could be expected when using our aerodynamic wheel covers on a semi truck and trailer combination. Using a standard SAE type 2 fuel consumption test protocol, the testing identified a 2.33% improvement in fuel economy. For comparison, additional data was then analyzed from the ECM on the same testing trucks, which showed a 2.44% savings. Conservatively, we recommend using 1% savings for 4 caps on the tractor tandems and an additional 1% when used on the trailer tandems for calculating fuel savings estimates for your fleet.

Result

Designed by pilots who know aerodynamics, these light-weight aerodynamic discs fit neatly on any 22-1/2” steel or aluminum rim in minutes — including super-singles! The unique aerodynamic design of or aerodynamic wheel covers allows air to flow more smoothly reducing wind drag and improving mileage to save the average truck driver $1,500 or more each year.
