Options for the Smallest Winter Wheels at best price for the M3 ?

[CanadianMetal]

For next winter , I was going to start looking into winter wheels and tires to buy for my RWD M3 .
As I like to just swap out my winter, for the all season wheels for a few months each year myself.

What is the smallest wheel you can buy ? at the best price ?

Are we able to get a wheel smaller than 18" that will fit ?
(as a thinner tire will dig into the snow better)

If not , are any 18" wheels considerably less expensive (compared to the OEM) ?

Or if cost savings are not much, is it best to just go with another set of identical 18" wheels , that the car came with , to mount winter tires on ?

Another option is to use your factory wheels as your winter wheels, and get nicer summer wheels. This is what I did.
