I have BMW "replica" wheels, 17" and Nokia Hakkapeliitta 7 as tyres.
This is how it looks:

And this is how it drives:
Extremly good traction on snow and ice, yet ok to drive on plain asphalt as well. Not too much noise.
AFAIK, you can get these even as size 20"

Of course they have tyres without studs as well, e.g.
