Looking for 19 or 20's on my 435xi GC Can i run a 19x9 all around? and if so, what would be the correct backspacing? I am also lowering on ACS springs

not sure of the backspace but an offset of +35ish will be fine. 255/35R19 all around?

can i do a 255/40? I'd like to keep the same sidewall if possible for comfort. And I assume these would fit 19x8.5 if they had to

Just add spacers to the rear of whatever squared setup you get to balance the look.

I'm running 20x8.5 +35 245/30 all around. Not too agressive, but fitment is perfect for what it's worth. You can probably do 20x9.5 +35 255/35 no problem, not sure about same wheels with 255/40. Might be too much.

Even with my very low profiles, comfort wasn't sacrificed very noticeably if at all.

What brand tire are you running? runflat?

Just bought 20x8.5 +40 squared set up, will I have fitment issues or need spacers?
