I have been on the elusive search for the "perfect" car for several years. I want fast, I want luxury, I want canyon carving handling and I want drivability in the city. The M550 was great, but the M5 beckoned. My base 2019 M5 proved to be too stiff in the city. My 2021 LCI Comp was spectacular, fixing many of the problems with the base - but, still too jarring (for a 130k car) in the city for me. The M850 is still stooopid fast, luxurious, rides better - at the expense of giving up some of the suspension goodies. It's also a bigger car and a heavier car. I don't know why they didn't give it the same tires and wheels as the M8. The OEM tires are really low profile. I don't know why you think I shouldn't have bought a sport model, when all I'm trying to do is get back to the size tires that were on my M5, and are also on the M8.
I've taken many 4,000 mile two week trips in the last few years. We go 300 miles/day and try to stay off the freeways. The car is a blast on the two laners, but obviously not M5 territory. It's most noticeable when I push it, but that's not really all that practical with someone else in the car telling you to slow down. (Sheesh. Women...
) The wider wheel I am also going to would help negate any increase in tire height.
As far as snow tires, sometimes you just need some effing snow tires
By the way, these snow tires were an 8" square set from my M550 - and they sucked for a car this big. But, they got me there and back. I bought the car car 2 days before the trip and it's all I could do. Luckily they were still in my basement. But, they are also the recommended BMW snow set for the M850.
Same trip, the next day
This winter I am running Michelin Alpin4 tires on the OEM wheels.........much, much, much better.

Its a twofer: more sidewall plus less wheel gap. I doubt is there is a single M8 owner that says, "Ya know, Ima gonna go down a profile. I just want more space between my fender and the tire."
