F30 335i Xdrive Staggered Wheels ISSUE
I recently purchased some new wheels for my 335.
Front: 19x8.5 w/ 245/40ZR19 Rear: 19x9.5 w/ 275/35ZR19 Wheels are originally off an e9x M3 There was a very noticeable stutter when accelerating... I've since taken the wheels off since I'm sure my xDrive system didn't agree with the new setup... I am wondering why this happens, if there is a possible solution, and if not, what size wheels should I try next... Thanks! |

The difference between front and rear diameters is 0.4%, so it should work. How much of a tread depth difference, if any, is there between front and rear?

Me
245/40/18 = 808 revs per mile 275/35/18 = 811 So 3 revs per mile difference... 245/40/19=778 275/40/19=781 Again, 3 revs per mile... You can't get closer than that.. Source: http://www.continentaltire.com/produ...7535r19-100y/?

Some mechanics at BMW told me that the xDrive system is so picky, that sometimes you have to try multiple types of tires before you find a tread pattern that agrees... |

I've used the exact same setup (wheel/tire sizes) for summer on my 435iX since 2015 - never had any problems
I go back to square setup with 18's in the winter

Im running 763m reps. 8.5in with 235/40R19 front, 9.5in with 265/35/R19 rear for my summers. Tires are Continental ExtremeContact Sports. No issues with my Xdrive.
I go back to the 400m squares for the winters. Will the computer go nuts if the xdrive is having an issue? With as many sensors there are on these things i would think something would throw a code? |

I wonder if x-delete will eliminate the 1% wheel diameter restriction on xDrive vehicles?

xdrive, 4motion, quattro ( haldex). I have an RS3 with staggered setup (OEM from Audi) 255front-235 rear. originally it came with Pirelli PZero , had 0 issues. then after some miles I installed Michelin Pilot Sport 4 , issues sometimes. then tried Michelin Sport Cup 2, issues sometimes. now my setup is 255-255 MSC2. 0 issues. In my 435 xdrive have non staggered setup and no issues. my setup front and rear have been: 225/45 , 245/40 and 255/40, 0 issues. conclusion, best thing is going square. |

Maybe it's the the overall diameter bigger or smaller than the OEM 26inches. Basically an rpm/speed mismatch.
