Comparison of square vs mixed set up on the M2 in this article :

Google translation :
Conclusion
Wide makes fast? Yes of course. With a few exceptions in the test disciplines, the wider rear-wheel tires in mixed tires actually increase traction and driving stability. And that's exactly what matters on the road. But more than larger tire widths decide the tuning and quality of the tire over optimal performance in all road conditions. When it comes to overall performance, Conti leaves nothing to be desired and drives the Hankook (235/255) and Goodyear tires at the same level overall. Hankook (235/235), Dunlop and the dry strong Nexen follow, Nokian pats wet. A no-go, because: Rain means the snow in the winter of Central Europe.

....If anyone masters German thanks for a better translation

If you own a car like M2, you are definitely an enthusiast and thus know how to drive a rear driven car in snow conditions.
Think it has to do with chains. If you keep 265 rear size or even 255 there is not enough space to fit chains, hence the 235 recommendation. Not sure though that many people will put chains on an M2... I will if possible (and needed to access ski resorts)

Because here we only can ride with the tire sizes recommended by the manufacturer, if we ride with 245/255 we are outlawed

But I don't understand how you can fit a 235 tyre on a 9" rim.
I thought it was strange, too, but I have now seen it with my own eyes and they don't look stretched or oddly fitted in any way. Considering that the 235 Michelin Alpin's are basically impossible to get from Tire Rack and other local sources, when I run down the set that came with the wheels, I think there's a very good chance I'll end up putting 245's on them rather than buy tires from the dealership to replace the odd size. I shouldn't have to worry about that for at least 3 or 4 years, though.

Is it possible to run 255 35 19 winter tires all-around on the stock 788M wheels?

The 641m wheels actually look much better than the 788m in my opinion.
Does anyone have any pictures of the matte black 641mís on a black M2C?

That's great that BMW offer winter wheels specifically for the M2 & M2C..

It's like their way of saying; "Pssss..You don't need an Audi Quattro, we got you covered"
