21 inch wheels on 2020 M550i, correct tire size?
Hi, I have a 2020 M550i x drive, got 21 inch rims, 8.5 and 9.5 wide.
Looking at Michelin Pilot sport 4s tires. 245/40 21 and 275/35 21. Trying to figure out if it will fit the car no problem, if it's a good size? Or should I go with 245/35 21 and 285/30 21? Last edited by Gemini_LT; 01-18-2022 at 10:27 AM.. Reason: Update |

I would personally not go over 20 inch rims as that is the maximum rim diameter fitted for the G30 from factory.
This would be the upper limit: 245/35ZR20 95Y 8Jx20 ET30 275/30ZR20 97Y 9Jx20 ET44 I see you also have X drive and by changing the total wheel diameter you can easily mess up the X drive system, it happened before. I am not saying that your setup would not phisically fit, they will, but you may end up with issues in the future: ride quality, vibrations, X drive issues, also your car will sit higher and your speedo will be slightly off. |

40 profil will be too big on 21s.

Hello, you should go with 245/35 21 and 285/30 21. I have 255/35/21 and 295/30/21 and the fronts rub sometimes. 245/35/21 and 285/30/21 would be perfect fitment.

With 21" wheels, you can go 255/30 front and 295/25 rear.
