Favor: F30 w/ N20 and M Sport
I was hoping someone could post a picture of their door jam placard, like the one I took below.
Please only do so if you have an F body... 3 series sedan... with N20 motor... and M Sport package. |

Reason I ask is...
My car came with 17 inch wheels as shown on my door placard... Ive since switched to 18 inch wheels (like what would have come on an M Sport or Sport model)... And I was wondering what the manufacturers recommended tire pressures were for that size. |

Thanks! Interesting to see the fronts remain the same at 32psi but rears increase to 35psi. Is that what you are currently running? Hopefully we can get an M Sport poster and then we have covered all the bases for N20. |

I didn't know you could get an M Sport equipped car with 17" wheels from the factory.

As a summary, this is what we have so far:
Base: Square, 225/50/17 (32 F / 32 R) Sport: Square, 225/45/18 (32 F / 35 R) M Sport: Square, 225/45/18 (32 F / 35 R) M Sport: Staggered, 225/45/18 (32 F) / 255/40/18 (32 R) Last edited by sspade; 03-09-2020 at 06:39 PM.. |

Seems like the consensus proper temp up front is 32psi. Ill stay there.
For the rears, Ill try going up to 34-35. Seems like a good idea since Im running a square 235/45/18 set up with aftermarket suspension. Most like the Sport model than anything else. |

I forgot to mention that I've got DHP (with adaptive suspension). I have no idea if that has any bearing on BMW's recommended tire pressure of 35psi in the rear. All I know is with go flat tires, DHP, and Dinan Shockware, the car rides great!

Interesting point on the xDrive. Wonder if that impacts factory recommendations. |
