anyways, JoeD, your logic is quite flawed. Because companies don't advertise that theier wheels are aerodynamic, they must not pay any attention, or do any testing to that?

Even IF Ef-Dee was talking about street wheels, and not bonneville wheels, doesn't make the point that the bonneville wheels are engineered to make the cars more aerodynamic any less valid.

Anyways, here are a couple links for you:

This article talks a little about the Audi A2, and it's aerodynamic wheel discs:

Any and every item that lies within the air flow of a moving vehicle will affect the aerodynamics. As much as you may not want to believe it, JoeD, wheels have an effect on aerodynamics.

But I will agree that a wheels aerodynamics isn't exactly high on my list of priorities when choosing a new wheel. And I don't suspect it's a very high priority for very many people, which is perhaps why it isn't advertised or developed as much as by the wheel manufacturers as other considerations (weight, aesthetics, strength, etc, etc)

Seems like some people tend to believe that aerodynamics of wheels doesn't matter simply based on the reasoning that Volk, Fiske, HRE, etc. don't advertise how aerodynamic their wheels are. :rolleyes: I think martini actually does have a point which was close to my point.

Too bad they didn't run the smoke streams down the SIDES of the car!&nbsp That would've given you a better idea of what's happening from the front wheel well.&nbsp Right now, my newbie eyes only catch vague hints of turbulence in the front lower rocker panel...

Yeah, I wish people would pay more attention to the aerodynamics of a car before adding huge rims and wings on it

umm not trying to flame or anything but those wheel arint spinning. when the wheels are spinning and the wind is hitting them like that they'll make a whole lot more turbulence.
Just my 02 cents,

i know wheels have an effect on aerodynamics, but i highly doubt the effect is significant.

i know rims on cars that only compete at salt flats are designed for aerodynamics. and i know that cars un the MPG battle use aerodynamic wheels and covers to rid the air of turbulance off the wheels (ala Honda Insight). but is someone gonna put flat, ugly wheels that do not flow any air to the brakes on their street car just for the added aerodynamics of the rim?? or is someone gonna put wheels covers on their RX-7?? get real guys.

i have seen no evidence whatsoever that proves different wheels are more aerodymic than other wheels. have you ever seen someone compare the wind resistance of a Volk TE-37 to an HRE 540?? yes, there might be a slight, insignificant difference, but thats it. like i said, if their was a difference in the aerodymamics of street rims, you would see manufacturers advertising that as a way to make more money. you think companies are hiding the data on their wheels?? no. why would they hide it if it can lead to profit??

i have not seen one single comparison of aerodymanics of different rims that are sold to the public. how will people know which rims are more aerodymic than the other if there is no evidence to support it?? by design?? :rolleyes:

yeah...and where is your reasoning that shows one set of wheels that someone can buy for their street car is more aerodymanic than the other?? :rolleyes:

and i never said the aerodynamics of a wheel does not matter.
