xDrive - 19" fitment help

Wheel and tire math doesn’t make sense to me at all so I need some help…

I found a set of wheels that I love that are:
Front: 19x9 ET25
Rear: 19x10 ET26

Would these work on an xDrive F31? And if so, what tires would I need to stay within the 1% rule for the xDrive?

Ideally I’d want these the sit flush or even slightly tucked. No poke.

Currently on Koni SAs and Eibach springs. Very mild drop.

Thanks in advance.

won't fit, will poke. offsets are too low for their respective widths.

Thank you dude. I recognize your username from other wheel threads actually!
What the lowest offset I should be looking for on a 9” width wheel that will get me flush or even tucked a few mm?

depnding on negative camber...255 on 9"@ET33-ET38 up front. you are not likely to find that kind of sizing unless it is custom width/offset. 285 on 10"@ET40-45 at the rear

for your x-drive F31, i'd do
235/40/19+265/35/19 on 19x8.5 ET32*+19x9.5 ET42* OR
245/35/19+285/30/19 on 19x8.5(or9) ET33*+19x10(or10.5) ET43*

* equals +or- a few mm either way

Personally I'd run 8" front and 9" rear with OEM offsets and then use spacers to get them to the offset / stance you'd like...

Or OEM widths etc

Keeps it easy then, more so with xDrive where it's tyre sizes that are paramount also
