Whats the widest wheel size I can go on a M850i?
Hey everyone. I’m thinking of going with 21” wheels for my 2022 m850i gran coupe & was wondering what was the widest I’d be able to go? I know theres a difference between the M8 & M850. Can I go wider then a 21x9.5 (front) & a 21x11 (rear) ? Also I wanna know if I have to use 255/30/21 (front) & a 295/25/21 (rear) or can i go with a 30 profile in the rear? Lets say a 285/30/21 or something like that? Any help would be appreciated thanks. 🤙🏻

Would love to see current pic of your setup and then an after pic once you lower it. Been thinking about upsizing similar to yours (when the car arrives) but keep factory height. Unlike my former vette I don't want to jeopardize this warranty by dropping in coilovers. Not yet anyway.

I have my fingers crossed won't have to mess with the camber, I don't think there's poke but a couple folks have looked at it and said maybe 3-4mm poke, depends on angle I guess. Probably b/c went with somewhat aggressive offset in rears (35et vs. stock 45et) Either way like it better than stock.

Could be the angles, but it does look like they're sticking out a fair amount. This might be the first M850 I've seen with 11's in the rear. I say that running 10.5 in the rear myself and having possible poke (it's kinda hard to tell, at least to me).

M850 is 8" fronts, 9" rears M8 is 9.5" fronts and 10.5" rears Quote:
I'm looking at the same problem. Only I have M5 706M (same width and offsets as the 813) wheels. Trying to use my old M5 snow wheels as M850 snow wheels. I don't think it will work. The BMW website even shows the M8 axel track is 10mm narrower on the rear axel and the overall axel width is 10mm wider (outside wheel to outside wheel). So, there's just more room for the bigger meats on an M8 under the fender. My other question is how much space is between the OEM wheel and the suspension strut. Some of this could be solved with more offset if the wheel can just snug up closer to the strut. |

Nope. No rubbing issues so far. Plan on posting pics at some point just haven't found the time to take decent ones.

Did you ever get a chance to post pics of your setup? I would love to see how it looks.

Are your wheels pushing outside the edge of the fenders? I actually have 12mm spacers front/back and have almost a flush look. I want to replace my tire with MP4S and thinking of going with 285/30/20 on the rear but worried the tires may go outside the fenders!
Any idea what is the best way to measure from current set up to get an idea of how it will look if I go with 285s? |
