I run what's on the door jam placard, because that's what I'm supposed to. No issues but I only have 6k on the car so I wouldn't expect to see any abnormal wear indicators for a while.

You can run 2 - 3 PSI less for a little more comfortable ride but I would not go less than that. |

Recently bought f30 320d xdrive but it has the 20 inch m performance staggered wheels.
Any advice on tyre pressures as the card in the door doesn't go up to 20inch. Thanks |

According to Tire Rack...
You should run the pressures listed on the door placard regardless of RFT, non-RFT, or size. |

2015 328i (probably base model), 17" wheels, Continental run-flats: Door sticker says 32 all around. I've been running 34, as it's comfortable enough and I hope to eke out a little more fuel mileage. Any higher on the cracked blasted streets here, and my car would start complaining.

Car rode on these cracked streets like a truck without shocks. I let some air out so that TPMS reads about 32, the placard pressure. Much more comfortable. If you live in a town as I do with the finest of Third World roads, unless you want to beat your car up or are a masochist, go with the placard pressure. You'll thank yourself. |

2017 440i convertible. 36/41 f/r. Per placard on door jamb. After about 45 min driving rears up to 44-45 psi. Question is: what if I drive for another 4-6 hours at 44-45 psi? Is this too high?

I thought I would leave it at 40psi for a while after a local indy shop recommended it, the 2 guys there are friends of the family and race and tune so I thought I'd try what they recommended.

Checked the tire pressures with a G.H. Meiser Accu-Gage. Turns out I have been running 34 all around, and comfortably. So I performed a TPMS reset, which you have to do while parked and with the ignition or engine on, and then drove the car for a few miles (such a chore, huh?) while the tire pressures reset. TPMS now says I have about 32 psi all around.

I once rode around horrible roads in Ireland for 3 days in a C class rental at 4-6 bar(~60 psi+, can't remember exactly) - it was a rental and I had no reason to check until a low tire pressure warning came on and I checked it at a gas station. The folks there were all dumbfounded. Quickly lowered to around 2.2 bar and carried on. Only noticed slightly softer ride.
So for those of you running high - tire wear might be an issue but the tires can take it. They say to increase pressure by 10psi for extended 100mph + driving. You aren't going to pop a tire at 40 or even 45 PSI unless you're running the ultra low profile minimum tire width for a wheel width or something. |
