Did Mercedes make Conical Seat wheels?

[Wusha]

Trying to identify these wheels and their seat type. I know they're not stock, but the retired man I purchased them from said he used them on a 420SEL before selling it, and he included his spare tire which had a OEM 420SEL wheel.

1989 420SEL OEM Spare (Ball seat):







Unknown Chrome Mercedes Wheels (KBA 43755):






You can see the OEM spare wheel clearly has a Ball seat. But the Chrome Mercedes wheels im not sure...It appears deeper than the OEM wheel seal but could they have used a different drilling method over the years? How dangerous is using Ball seat on Cone seat wheels? If anyone has experience, please comment.

I cant find pictures of Cone seats online. I mainly find images from ebay or markets selling lugs. Screw it, i'm going to order a Cone set and see what fits.

I don't recall seeing any Mercedes OEM rims using a cone insert. I imagine using a cone style seat with Mercedes ball lugs would be bordering on a very marginal limit of safety and I wouldn't do it. I might do it in an emergency situation but I certainly wouldn't trust it for a long term use.

Why are you going to randomly order parts?

Take a ball seat, bolt, give it a thin coat of grease then place it in the wheel you want to test and see if it transfers. Also test it on a known wheel.

What are the marking on the back of the unknown wheels?

I know but I’m learning. I had a feeling the ball seat lugs were loose. The 40mm 12x1.5 conical lugs fit perfect on the front hubs. The rears has to be cut 5mm to clear the parking brake. I used the play doh trick to see the lug hole seat.

Used a band saw and a bench grinder to smooth it all out.
