I was figuring that it could get in through the center hole that allows clearance for all the components going to the wheels

Where I live it's pretty dry, and although we get rain & puddles, it's not a daily (or even weekly) occurance. I would say, if you're afraid of water getting trapped in there, about 3 small "drain holes", maybe 1/4" to 3/8", near the edges of your discs should do it. The centrifugal force of the wheels spinning should pump it out of those drain holes in short order, and the aerodynamic penalty should be minute. Even notches cut into the edges of the discs might work even better for that.

cheap inside wheel covers

Here is how I covered the inside of my Insight space saver wheels on the red VX to make them more aero. These are the wheels I put the vinyl covers on the outside to make them smooth and aero. Since I used supplies I already had on hand I think I will see a breakeven in MPG in at least 15 years.














There were 4 "holes" that were larger than the foam ring, so I duct taped them before I inserted the foam ring on the wheel





So far (1500 miles) centrifugal force is all that is needed to keep the ring in place.





Outside of this wheel
