Picked up new ride yesterday!
Valencia Orange over Black x1 35i M sport. Love it, drove great, got compliments on the color already too. However, checked the tire pressure for the hell of it and it was @ 56psi on all 4 tires! Are they NUTS at the dealership?

I take it you checked the pressure on cold tires, i.e. not right after driving, nor parked on hot tarmac? Cold, the pressure on an M-Sport 35i should be 41(front)/44(rear), assuming you have staggered 18" tires. Somewhat more for 19". Adjust up or down a bit depending on altitude, weather and road conditions. I like my fronts slightly lower. |

Sounds pretty sick! As for tire pressure, something in the 45-50 range would be about right for cold tires. if thats after driving home - bleed a little air out! :O they're nuts!

Congrats. Enjoy it!
Is the PSI spec'd that high on 35i 18s? That's kind of nutty high for cold pressures. |

With AS tires or without the increased top speed, the pressure should be lower. |

Yes, they were cold. Checked them first thing in the morning. My door sticker says 35 front/ 41 rear - I have the non-staggered 18" Pirelli A/S RFT's....

My advice is to go to a service station with nitro and get them filled to the right pressure, and then reset the pressure sensor monitor. Nitro will cost you a few bucks, but the tires will hold the pressure better, so you don't have to overpressure to compensate for 3-4 months of future driving. |

Wow those all sound high. My 28 M Sport with 18" staggered summer performance says 35 front and 38 rear. My E93 335 with sport package with staggered 18" summer performance says 32 front and 39 rear.
