Bad Wheel fit

So, first of all - I don't do my own tire/wheel changes. It costs close to nothing at the shop, I don't have a flat working area and my Subaru needs to be programmed anyway. The shop is literally next door, they will even valet-fetch the car from my habitual parking spot.

When I bought the Levorg, it came with a set of winter tires on. I had them swapped off and on again, but at the inspection the dealer took a look at them, and told me, he wouldn't fit the wheels again, as the conical wheel nuts were too small for the wheel.
I went back to the dealer and the wheel manufacturer, and they all told me, that those wheels were indeed certified by TÜV and only to be mounted with the series wheel nuts of the vehicle. Manufacturer told me, that "it doesn't look pretty, but it works"

This time, even the shop where they mounted the wheels last time, complained that the fit was really shitty, and the wheel nut sinking way too far into the wheel, with the contact patch between nut and wheel being too small for real comfort. The wheel is already clearly marked from being torqued into place, and most of the techs tell me it's a broken wheel/rim in waiting.

I'm thinking of going back to the manufacturer yet again - or just buy a new set of wheels for next winter, and ride them for a fourth season, then trash them, because they're pretty low quality anyway.

Any suggestions?

Some aftermarket wheels use a different lug nut surface than OEM wheels.. Sounds like this may be your problem. Most tire shops should have been able to recommend (sell) you the correct lugs to correct the problem.

Sadly, that's not what the certification document indicates - there it's specifically stated, that the only lug nut certified for use on the public road is the OEM Subaru one. (And my OEM wheel set for summer fits perfectly fine.)
Either my entire wheel set is a dud, or it's just a crappy design...

certification document? oh come on. your not oem wheel may need a different lug. are the wheels on this hub centric or lug centric? maybe give us a picture.

This is Germany, each wheel has to be certified by the TÜV for road use, including how to fit it to the vehicle.
There is an ABE document (https://www.oxxo-wheels.de/wp-content/uploads/Gutachten/felgengutachten/Oberon 5 (OX08)/7,0x17/5x114 ET55/OX08-7,0x17-5x114-ET55-56,1-Sub.PDF - obviously in German) which also mentions M12x12.5 lug nuts, as an alternative - but I assume that would be identical in size to the OEM ones, as they're noted as being an just alternative choice to a certified and tested combination.

I can give you some pictures, but the ABE document (and I did check if it applies to the wheels) outlines the spec at least.

Yeah, I've seen lots of TUV wheels in the US that require different than OEM lugs, due to ball vs tapered seat of the lug nut.

Whenever they do, this will be documented in the ABE-documentation. That's not the case here. The manufacturer also indicates, that they should fit with the OEM nuts, after I checked in with them, describing the bad fit.
