In Europe, you can NOT order the 21s Winter Wheels, only the 19s, when you order the P85D.

I guess that confirms that whatever version you order, 19s will fit, winter or not.
Also, when you look at the Specs page on any EU site, you'll see no difference about calipers or disc sizes which could prevent 19s indeed.
My take is this is just some monetization trick (like the one about having to order the panoramic roof to be able to install a roof-rack).
Plus a real pain in the arse if you blow a tire on a week-end trip: 19s tires are already not often "in stock" at the local shop but getting a 21s ? You'll be AWOL for some days just waiting for the delivery ...
