I'm struggling with this very issue. 21" wheels in snow country is worthless as a year round solution.
I can appreciate that California customers don't have this issue (for the most part).
However, it forces all of us in snow country to buy a second set of wheels/tires unless we just trade the 21" wheels for 19" up front.
If we do that it means that we're paying an extra $3500 for nothing.
Doesn't seem like a very customer friendly situation to put all the snow country customers in.
People who live in real snow country know they can't use the same wheels year round anyway, so we would get a separate winter wheel set even if we got the 19" wheels for summer use.
I'm going for 21" perf.wheels in summer and 19" studded tires (Nokia Hakkapeliitta 7) in winter.
