Tire pressure cold
Does anyone know what temperature on iDrive BMW meant for cold tire pressure 36/39 PSI? I noticed with this cold weather nowadays, it is 1-2 psi below the door sticker, though pressure rises when i drive the car , same for temperature.

It's my understanding of tire pressure that what is on posted on the door label is at cold temp. But I don't know if they meant 0 or neg degrees. lol

You've simply seen a drop due to ambient temps. You'll likely see that come up as ambient temps come up.

So at lower temps, the tire pressure will read lower. Same if the tire temp is warmer than 68°, the pressure will be higher. Of course this applies only if the temp of tire is 68°. |
