Staggered Setup?
So as we all know the standard tires and rims for the M240i are either 19" (front & back) with 225 front & 255 rear (if you got performance non- run-flats) or 225 all around (if you got run-flats). The new M2 coming out has a staggered set up with 19" in the front and 20" in the back. I was wondering if it's possible to do on the G42. Should be the same chassis but I know the fenders are a bit different for the new upcoming M2.
Thoughts? Or are we stuck doing 19"s or 20"s all around.

As long as the outside diameter of the tires are within 1% should be fine

1% of original tire diameter or 1% relative to new tires front to rear? Also if new tires have a different diameter can the speedometer be re calibrated.

1% relative front to rear to keep xdrive clutch packs happy.
That being said, I aim to also stick to approx 1%-2% rolling diameter. |

Don't mean to necro the thread but on my build sheet for the performance run-flats it says 225/255. Mine is a 2023 was this a change made for the 23s by chance? |

However, it didn't add 840 for speed limit increase for 2022 from the guide though. Last edited by inc235; 09-15-2022 at 11:08 PM.. Reason: comment on 840 option |

The terms "tires" and "wheels" may be used interchangeably at times, but they are not the same thing. Wheels are the rims on which tires are affixed. Tires are rubber ovals that are installed on the wheels.

Incorrect, one of the available options is a performance run-flat option. I wouldn't take it, but it's one of the options. And not a new concept, my 2009 328i had Bridgestone Potenza RFTs.

Oh wow. Well I mean I think it's counterproductive to make a performance tire a run-flat cause it'll be unable to sustain higher top speeds than a non run-flat.

I agree. I changed it last minute after learning about the speed limiter on A/S. I'm just going to order some Michelin pilot sport A/S for a year or so then get some proper summer tires.
