Looking for someone to chime in on wheel gap differences in Tire Size for xdrive.
My car is lowered on Dinan springs and bumpstops - for those that know, it's a conservative drop - not that low at all. The wheels are: Front: 19x8.5 +35 et Rear: 19x9.5 +40 et The tires will be Michelin PS4. For tire size, my preference is: Front: 235/35/19 Rear: 275/30/19 This is an equal rolling diameter (for xdrive) I have seen others use: Front: 235/40/19 Rear: 265/35/19 Rolling diameter is (0.4%) I'm not a huge fan of the above because the tires look a bit too beefy for me (making the wheels look smaller) and I prefer the wider 275 tire for the rear. Another option is: Front: 235/40/19 Rear: 275/35/19 Rolling diameter is (0.8%) Again, this would mean a beefy tire, but it would be a 275 in the back, which looks nice. Can someone explain what the wheel-gap differences will be with the above sizes? Also, can someone explain what camber will be like in the rear? I don't want to run an overly aggressive camber. I have done that in the past when my wheels were 20x10.5 et45 - tire size was: 275/30/20 - I didn't like the way it looked - tire was stretched, and the camber wore out the rear tires on the edges. thanks for your help |

There's gotta be some folks out there with their thoughts..! Anyone?
Research seems to say that if I go with, Front: 235/35/19 + Rear: 275/30/19, the diameter will be smaller than Front: 235/40/19 + Rear: 265/35/19. Car is lowered on dinan springs, but definitely want the wheel arches full. |

For xDrive most either run 235/265 or 245/275. I'm running 245/45r18 square which is the same diameter as 245/40r19. As for your rear wheel/tire selection, 9.5et40 is about 8mm further outward from 8.5et35 I run currently.
I have a few photos here of my current setup: https://www.bimmerpost.com/forums/sh...php?p=25078893 I'm at most 1/4" higher on Eibach's than I was on my Dinan Springs.
