I have a set of 759i's waiting for the tires on my 664m wheels to wear out, which should be in a couple of months, or no later than the next rainy season. I was thinking of going with the 664's (19") on the front and the 759's (20") on the rear. This is basically for looks only as I'm pretty sure there's no effect on handling.

Thoughts, good or bad. You can even flame me, if you want

Some M cars are like that, by design ; can’t remember which one, g80 m4 i think

I'm not sure the styling of the car will be cohesive with staggered diameter wheels. .....but who know.

Functionally, I don't see a problem as long as your overall tire diameter is within 1% (if it's an xDrive.) If it's RWD, I don't THINK it will cause a problem but I could imagine a scenario where it might confuse the stability control. Not sure if it only measures side to side rotation.

The overall sizes would be pretty close to the same. I'm pretty sure (haven't looked yet) 245/40 up front and 275/30 out back should work; they are stock sizes.

I'm still on the fence and have a few months to work this out.
