I've posted this query on the bimmerpost forum but have not received any responses. There are a bunch of well informed, knowledgeable folks here on BITOG so I thought I'd ask the question here, too.
I am currently driving a 2022 BMW M760i. Previously I owned a 2019 Mercedes AMG S65. I have a spare set of rims for the S65 to which I mounted snow tires and used those rims with the snow tires on them for winter driving. Being the frugal person that I am, I'd like to use the existing AMG rims and snow tires on the BMW. I've checked the rim specifications on both the BMW and on the AMG and they are both the same with the exception of the offset on the front rims on the BMW being different than the AMG. I can compensate for this difference with a spacer so in theory, I ought to be able to use the MB rims on the BMW. Here's where there may be a gotcha. The lug bolts on the BMW are M14x1.25 and on the AMG they are M14x1.5 but the AMG rims require a spherical section between the head and the threaded section. So, I need kind of a Frankenbolt. It needs to be M14 x 1.25 which does not appear to be a problem but I've not found one in that size with the spherical section between the head and threads so it'll mate with the AMG rims. Is someone aware of some somewhere or someone who makes custom bolts in small quantities that might be able to make something for me? Thanks in advance for any assistance that can be offered.
 
Far be it for me to criticize what someone drives. However, being the frugal person that you say with a $80k car you plan to drive in the snow, either park it and get a 2015 X3 as a winter beater or get the GD proper wheels and snow tires for the bimmer and sell the MB wheels/tires.
 
I would need to see the bolts being described. I'm picturing the one needs a set made for HUB centric mounting not LUG centric.

My Sequoia had Hub Centric alloy rims but some came with Lug centric steel spare so the lug accommodated both. Of course OP needs bolts not nuts. This was Sequoia lug nut.

Trying to as the Brits would say Bodge something together doesn't sound like a good plan with rims and expensive hardware.

I would try to find a used set of properly sized rims.

Yes you have. And very relevant ones at that. All came within 24 hours of you asking the question, and the thread (opened ten days ago) ends with a question to you (back then), which you have not answered.

Is it wise to run spacers on snow tires? What about corrosion? Won't they throw more ice and sand onto the body?

No, he said compensate, meaning he can bring the offset of the AMG wheels to be in specification for the BMW. The AMG wheels are probably a higher offset.

I don't see much opportunity for an increase in corrosion when using an anodized aluminum spacer between an aluminum wheel and coated brake disc, vs stock.

Wheel spacers and adapters are common.
 
Thanks to all who responded for all of the replies.
Vercingetorix, thanks for the suggestion. I think what I need, though, is a ball to conical seat conversion, I'll check to see if ECS tuning has something like that.
Egg_Head - Thanks for the suggestion. That was my first thought. The wheels have been for sale on an MB forum for a couple of months now. So far, no takers and based on what I've seen as far as asking prices, I'm selling them cheap and would just about take anything for them to get rid of them.
The_Jeff_ Thanks for your suggestion also, that may work.
goblin - Should have worded my post better and said so far I've not received any suitable suggestions. If you're saying I didn't respond to the questions about wheel size, that's not the case. I posted a table with the pertinent information in it. I believe that was the same day as the question was asked.
 
Vercingetorix - ECS does have a set of ball to conical seat conversion inserts. I'm going to order a set and check them out. Again, thanks for the suggestion.

Once again, thanks to all who offered suggestions.
