You're actually pretty much right on target for what I would do.

I would go with a 16" all season, as the sidewalls on them are less stiff than on summer tires. In fact the Conti ExtremeContact DWS 06 would likely be my tire of choice.

So I would have three sets of tires/wheels to choose between depending on my driving needs at the time. As long as everything is on their own wheels, swapping between tires is a breeze!
