I usually swap my tires in the winter, I assume the 20s wont be too bad in the winter with dedicated tires.

20s would be fine, I don't even know if they make 21s in an appropriate winter tire. Depending on how long you own the vehicle, it might make sense to buy a cheap set of wheels and avoid paying the mount and balance cost twice a year.

Coated my 718m's with gyeon rim and cleaning is easier.
Definitely consider a winter set of wheels and tires. Getbmwparts is selling a full set mounted, balanced and with TPMS. |

I am real happy with the looks and ride quality of the 21" wheels, but if I had to do a lot of winter driving with my M40i, I would get a cheaper set of winter wheels with all season tires or winter tires. The summer tires on the M40i are not going to do well in the winter, no matter if you have the 20" or 21" wheels. And winter tire options, or even all-season tire options, are somewhat limited for both of those rim sizes in staggered setups. I'd say get whatever factory wheel you like the best, and then plan on a set of 19" wheels/tires for winter. |

I have the 21”s, I also bought a spare set of 695 20” wheels with winter tyres.
I swapped them back recently as the winter has been so mild recently. The 21”s are runflats the 20”s are not. The difference is negligible, I actually prefer the sharpness of the 21”s. Then there the looks, the 21”s make it. |

I now have a separate set of winter tires/rims, went down from the summer 21" to winter 20" non run flats so the side wall is softer as is the rubber compound but the ride is almost exactly the same. I have pirelli winter scorpions in the staggered sizes, rear is wider. the stock summer tires were less than useless in snow, do NOT drive around in snow and ice with these tires they will get you killed. fyi I put a "slime" kit in the storage area since these are not run flats.

Had concerns but thanks to this forum I stuck with the 21” and very happy. In comfort mode the ride even on UK Hampshire roads is very good. I feel the 21” wheels set off the X3 M40i, without them it could be any X3

I originally was irritated that the 30i MSPort pkg did not have the 21s as an option.....but grew to love the look of the 20inch 699s. Now that I have them Im happy I got them. Really good balance of comfort and style

I'll be doing this Saturday in a separate thread when I do a photo shoot, after I get my spacers installed

I fretted for days last month before placing my order, debating 20 vs 21 ad nauseum. Although I was queasy about 21's tire replacement cost and apparently short tread life, I chose 21s because they look awesome and are exclusive to M40i.
Two weeks in, I do not regret 21s although I have learned they contribute to a jittery highway ride and are VERY difficult to clean. I always wash by hand, and found the 21s made me work for it. Somehow the brake dust and grime seem to bond to the wheels. Anyone have advice on a cleaning product that is safe for these wheels? |

Personally I hate the 718M wheel design and the colour looks a like matte brown to me. I like the 648M 7 Series wheels and fitted them to my M40i. The 20" wheels with a bit more tyre sidewall are a lot smoother than the 21's yet the handling and corner grip feels the same.

I saw a white M Sport 740i sedan with these wheels and looked great and had the same visual impact on the M40i and worked well with a white X3 I thought. The 648M wheels have a decent dish too where the 718M's wheels are quite flat. |
