Picking up '15 f31 M Sport xDrive this week.
Already looking into replacing the wheels and need help with figuring out measurements.
I'm thinking 19s. Planning on getting some coilovers also in the near future. Where would I go to calculate wheel sizes/offsets that work with specific coilovers? Or is this going to be trial and error?
Since xDrive, I'm thinking staggered isn't a practical option??
I'd also like pretty wide tires if possible with a flush-to-fender look. Obvi want to avoid any and all rubbing.

for square. 19x8.5 or 9, +35ish with 255/35/19's

for staggered. 19x8.5 or 9, +35ish with 245/35/19 front, 19x10 or 10.5, +42ish with pretty wide 285/30/19 rear. diameter difference 0.4%

or 19x8.5 +35ish, 19x9.5 +40ish with 235/40/19 front, slightly wider 265/35/19 rear. diameter difference 0.4%.

bilstein and kw offer coilovers for xdrives.

THANKS. Where did you find this info? Are these measurements all that will fit, or can I get something wider and make it fit? Also, what are your thoughts on staggered for xDrive?

i find my info from these forums and using the function

bmw offers x-drive with staggered if you option mixed performance tires. overall diameter should be approximately 26". to avoid problems with the x-drive transfer case overall diameter differences between front and rear should be kept as close as possible and not exceed 1%. some have not have issues with 1.2% but why risk it...

wider? why? heavier wider tires=more rolling resistance=less fuel economy=more wear and tear on your x-drive transmission=expensive tires=makes already slow n20 an absolute slug.

if you don't care, you can do wider with additional negative camber. the widest without is additional -camber is 255/35/19, 295/30/19. http://f30.bimmerpost.com/forums/sho...ray340i&page=4

if you want to get more crazy then please review this thread. it's not my "cup of tea" but sounds like it may be yours. http://f30.bimmerpost.com/forums/sho...d.php?t=909786

Thanks again. Yeah, as I noted, I'm relatively new to this and still finding my style preference.
