My Acura RSX Type-S does this... 17" 5-spoke wheels that have very large openings between the spokes.
I was hoping the Outback I'm waiting for would have rims wouldn't do this.. I know they have smaller openings than my RSX.
It is a rare thing though.. it requires just the right amount of snow of just the right consistency at just the right temperature..
You end up just needing to pull over and take your ice scraper and knock the hardened snow off the rim.
There is probably some treatment you could put on the rim to make it hydrophobic.. but that's probably not something you want anywhere near tires or brakes.
