So I contacted the dealership about winter tire recommendations today. They got back to me with the same summer size of 275f/315r. They didn't say what tire they were offering, but the quote was 3,680 swiss francs. I'm not lying, and this is just for some tires. I've done some independent searches and that quote is about 2000 more expensive than the Pirelli Ice and Snow RFTs. The dealership is having a laugh.

Anyhow, regarding the 275s on all corners, I saw that the maximum recommended width for a 275 is 10''. The rear wheel is 11''. Anyone have a comment on this?
