Wheel Covers

Yes....when combined with other fuel saving techniques. MVT boast a avg mpg of 9.5 with all their efforts...and it works! They give a new Harley to the top MPG driver every quarter.

Alone, I doubt they offer much to talk about.

 

I have them on the ride I will be getting rid of next month. I am not sure they do anything for aero. I put them on because i hated to shine aluminum and they looked good. Mine are polished stainless steel from Real Wheels.

 

Does they SPIN?

ducks...

 

I'd say that they work when you're running at 65mph and above on LEVEL terrain. Add elevation changes into the mix, and your gains will evaporate, IMO.

 

I started with the Deflecktor ones that are made of canvas with zippers like Schneider uses on their trucks. Only $50 per wheel.



Even painted them.....




When I switched to Super Singles I went to the Real Wheel Stainless Steel Wheel Covers that look great and only need Windex and a rag to make them look like a mirror. No polishing. I paid $505.63 for all for drive wheels. The aluminum ones are cheaper, but the look of stainless steel is hard to beat.



Here is how they mount with a bracket fastened to 4 of the drive axle hub nuts that has 2 screws to fasten them to the bracket.



As far as fuel mileage, they might add 1/10th to 2/10th better fuel economy that is real hard to measure that low of a gain with the 4 added to the drives, but I love the mirror shine look and the idea of not having to polish my drive wheels again.

They will hold in heat because I use TST Tire Pressure/Temperture Sensors on all my tractor wheels that I highly recommend to everybody weather you have wheel covers or not. Found a brake dragging due to air leak on one of my drives last week that can cost alot of fuel mileage. It wil pay for itself in one road side service call for a tire or with fuel savings to keep tires the right air pressure.

Here is the TST Tire Monitor System I use....


Note: I also recommend to add the repeater for the tire system because the wheel covers make the signal weaker.

Good luck on whatever choice you make to do and I hope my post was some help to anybody interested in wheel covers or tire monitoring systems.

 

I know a driver who put them on his T660 and claims they give him a 2/10 mpg increase. I think in conjunction with some other aero add on like air-tabs etc they may all contribute slightly. Depends what type of truck your putting them on, if I put them on my w900 I doubt they would do a thing but on an allready slippery truck they could possibly help. I am a bit sceptical of claims of 1/10 to 2/10 mpg gains as that is such a low gain that it's hard to contribute it solely to the wheel covers. Just my thoughts.
