This subject has been bandied about several times. The obvious/easiest solution is the R 17" wheels with appropriate tires.
I have presented thoughts in the past on alternate schemes. One is to use narrower wheels with less offset. A 7" or 7.5" wheel combined with a narrower tire is a better choice for "real" snow work.
That narrower width allows less offset and perhaps more caliper clearance.
You just need thin spokes on even the narrow wheel. Tirerack has yet to offer anything.
