DUMB Wheel question
 
https://www.hubcaphaven.com/mm5/grap...wheelcover.jpg

will taping over the little vents/holes in my hubcaps for long trips help with aero or mpg? obviously they are there for brake cooling, but i dont plan on doing any braking while driving for hours in the middle of nowhere on the interstate with cruise control set to 90mph...

would duct taping over the holes just for a day add any benefit? even if its 1mpg?

Those hubcaps look already quite aerodynamic, I wouldn't hold my breath for an actual MPG improvement if you cover those vents.

The dumbest question is the one you didn't ask. ;)

That said, I agree those wheels look pretty aerodynamic already. If you have time to test the duct tape mod, it would be nice to have actual data. But I'm guessing any benefit would be marginal.

Edit to add: Maybe you could use your road trip as a mpg test. Use the duct tape mod for half the trip, and remove it for the other half. See what happens.

Are all 4 identical, or do you have symetical caps for left and right?

I had aero caps on the Prius where all 4 were identical. That meant half appeared to be facing the wrong direction.

Just checked. Yeah they must all be the same. Cuz the two on the left side of the car are facing a different direction than the two on the right side haha

So it can't hurt to just do the two on whichever side is retrograde to the direction of travel.

What do you mean? And Iím gonna try to tape over the holes for the long trip to Arizona. If people can do pizza pans and survive city traffic, I think I could survive highway

'Can't hurt' or 'retrograde'?

Can't hurt = not worth doing.

retrograde = the side that sucks air out instead of in.

Aluminum tape looks better than duct tape, and leaves less residue.

I taped them up. Let’s see if the dollar tree grey duct tape holds on! Blends pretty well
