Sorry I'm a dunce when it comes to wheel and tire fitment. I have a square set of winters from my x3m that i sold recently. 20inch square setup. 255 45 20 setup (20x9 +35mm)
I "assume" they should be okay to use on an m40i but wanted to confirm. In the event they dont I need to start shopping lol

First two in the link are the stock sizes for a staggered setup. Square would just use the first tire size only. Third is your tire.

This is super helpful. Thanks so much. So being that I'm within 3% I should be able to get away with it for a few short winter months. That's also contingent upon the bolt pattern as well. I assume the g01 and f97 share the same bolt pattern (fingers crossed)

I believe its been mentioned here that F97 is 5x112 which is what G01 is. But I'm not 100% certain.
