Thanks for the reply. No issues with accelerating or studdering right?
Asking because of this issue I’m trying to narrow down: https://g30.bimmerpost.com/forums/sh....php?t=2028427 |

Ah ok. I’m Stage 2+ and was advised against going one step colder. So I returned them and installed stock plugs, HPFP, and downpipe and flashed Stage 2+. Now two weeks later I’m getting the misfiring. The wheels is just a coincidence. Thanks bro!!

That’s probably why you have the stutters, it’s actually misfires. I would swap plugs ASAP before consecutive misfires happen, shutting down one of your cylinders. Happened to me, and that’s only on Stage 1. |

The car did not like the size combo with the tires I’m running. The tire size hesitation was felt only under normal acceleration from a stop and when coming to a stop. After fixing the gap, the car still had good power, just the jerky take offs. Changing the front tires to 245/35 solved this issue. |

Great info here. Anyone have suggestions for wheel color on a skyscraper grey with XPEL stealth M550i? Thinking I’ll get a pair of 20” with summer tires and use my 19” AS run flat OEMs (in black) as a winter set.

https://tiresize.com/calculator/ And 255/35/20 isn't an OE front tire size anyway. The main thing from I was trying to point out is to try and achieve under 1% difference in rolling diameter. But I did also just checked the OE 20' size and the 245/35/20-275/30/20 is also a -1.1% different in diameter so I guess in the grand scheme of things if BMW runs that then its fine. When I researched this xdrive staggered before I would always find the rule of under 1% of rolling diameter difference. |

Posting here because the OP helped me decide on my fitment. Same HRE fitment except with FF11s. Michelin PS4S Rubber is 255/35/20 Front, 295/30/20 Rear. 2020 M550i w/ dynamic suspension. I would say the front is flush and the rear has a little poke. Went with 295 for 0% rotating difference. Rear tire looks a little stretched on 10.5 rear. I actually made the mistake of going with the PS4S, when originally I was looking for the same fitment as OP then realized he had all seasons. Once I saw the rear stretch, I was pissed...until it was mounted. After seeing the 295 rear PS4S mounted, decided to go with Dinan springs to complete the look... And I will update after. Picture is before Dinan.
Just getting started... Last edited by planbmike; 03-21-2024 at 06:56 PM.. |
