Vented mudflaps ?

Not many have driven the tractor only comparing regular mudflaps to vented mudflaps

It pays more to haul freight.

 

if you want to save fuel buy the mud flaps that really flap not the stiff ones. i think the fuel you would save would be about the same as hanging your arm out the window when you drive. all the drivers did that b/4 they had a/c in trucks be safe out there

 

1-3%? They are so close behind the tires I don't think it would make that much of a difference.

 

See them on lots of Gemini/Loves trucks. Don't believe for a minute they give that large an increase in mileage. Their drivers just think they are cheaper and that's why they are put on as needed. They are much lighter then a really thick flap.

 

You don't want them, states like Arizona will write you a ticket for a "sailing" mud flap. I think a 1-3% increase in fuel economy is a far stretch.

 

I put the Eco mudflaps on truck and trailer.I don't now if is any fuel saving with them .

 

What I would like to see is these miracle fuel saving mud flaps in a wind tunnel test. I can only imagine the wind will go thru them and swirl in hundreds of places, creating drag, which decreases efficiency.
