My personal perspective...
I've bent countless rims ; well over $10,000 worth of AMG, Brabus, Kinesis and OZ rims ruined beyond repair and sent to the recycler. My worst case was I got $50 from the recycler for the weight of the aluminum of what started as something like $4000 worth of Brabus rims; a complete set bent within about a year or two.
And I believe that's with more side-wall rubber than the Polestar 20" or even 19" rims will have.
So if it isn't already evident, there is no way I am paying that amount for the 19" Polestar rims for use as winter rims.
I'll be hoping the guys at the Tire-Rack gets hold of a Polestar and does some test fittings with numerous rims as they had with the Mini JCW when it came out . I'm expecting the OZ Ultraleggera and some others to fit our brakes and cost 1/2 the amount or less of the Polestar rims.
That's just me. Please deduct $0.02 from my account.
