No experience with run flats, but why not just keep a set of chains in the car 'just in case'? It'll be a last resort measure for any bad snow/ice. If there's a lot of snow the ground clearance of the f31 (or lack there of) will really be the thing that holds you back. When I drove in Lake Tahoe in 'AWD or Chains' conditions an AWD car with all seasons would've been fine. If it accumulated another 3" or so an SUV or truck or snow tires with good tread would've been needed.
I can't imagine the rubber compound for any AS (run flat or not) will be good enough for true winter conditions.
