Aero Wheels

Help me out with this. Is there a difference in mileage between the three different wheel/tire choices? Folks on the Forum quote a 14% mileage loss if you remove the wheel covers on the aero. The exposed wheels look awfully similar to the other 19" choice and the 20" as well.

I experience a slight (~3-4%) hit when I remove my aero wheel covers. No way is it 10% or more as some have indicated. I like the looks of the exposed wheels underneath the aeros. I put the aeros on only for long trips.

I also took the aero covers off pretty much first thing. I think the efficiency loss with the 19 and definitely a 20 are more due To stickier tires and more rotational mass with larger wheels. Than aerodynamic inefficiency. In general smaller Rims Excelerate faster, stop shorter, and are overall more efficient.

The "real" EPA range goes from 332 on a M3LR 18 w/aeros of 273 on a M3P 20". The M3MR runs from 237 to 262 depending on tires.

"to" not "of"

There have been a couple of high-quality tests of aeros on/off, and I'd suggest that the difference is between 0 and 4% - 0 to 12 miles of range - depending on whose data you trust.
There's a bigger difference between the 18" wheels and the larger wheels.
