I was looking closely at the aero details on a Honda Fit yesterday.
When I looked closely at the wheels, I could hardly believe what I saw:
Ten large holes on one side, nine smaller ones on the other.
Irregular spacing of the smaller holes too: (Click to enlarge.)
Why is the hole pattern in the steel wheels asymmetrical?
The wheel is covered by a wheel cover, so I doubt it is directly aero related.
To reduce wind noise created by the wheel spinning?
To minimize structural resonance in the wheel itself?
If the latter, what about the untold millions of symmetrically holed steel
wheels on the road?
Somewhat related thread:
Why do most wheels have 5 spokes?
The devil is in the details.
