340i xdrive - will 356 rims fit?
So I just picked up a set of 356 wheels. I was under the impression they were a square setup, but they're not.
They are currently on 245/35/20 and 275/30/20 rubber that is in good shape for a winter setup. I'm pretty sure they're 1% difference in diameter/circumference. Will that work with my x-drive or do I need to take them back/get new tires? I currently am running (on factory optioned 624's) 225/35/20 and 255/30/20 which are .8% difference. I am in a 2016 340i xdrive. Thanks. Last edited by 73vette; 11-29-2021 at 12:34 AM.. |

245/35/20=26.8"
275/30/20=26.5" difference is 0.97%=1% ok for x-drive. diametrically, 235/35/20 up front would pair up better with a 275/30/20 rear if x-drive. fwiw, those rims are 15.6kg=34.3lbs each. with larger diameter(taller gearing), wider(more rolling resistance) and heavier tires you should expect to feel a significant difference in acceleration/braking. not that you're accelerating or braking hard in the winter...just sayin' |

Yikes, they are heavy. Current 624 style weigh 10.4 and 10.55kg each.
Just good to know they won't mess with the xdrive (in a bad way). I have the track package w/bigger brakes and stage 1 bm3, but will be sure to try to behave with the throttle. |

in this link is 245/35/20 et35...https://f30.bimmerpost.com/forums/sh...54&postcount=1, yours will have 2mm more lateral clearance. consider 245/35/20 is a nominal size designation and actual tire size between tire brands/models of a given size vary. .
