38psi is pretty steep for daily driving and BMW's recommendation typically allows for a full load of weight in the rear cargo area. So if the car is never loaded up that heavy then you shouldn't see a situation where you need that much.
I stick to 36F and 33R which is a very comfortable ride and results in no uneven tire wear.

after you decide on your desired pressures. you can reset the TPMS system and have it learn the new pressures.

Tried this out earlier today and I was really surprised at how much it changes the ride. It wasn’t too bad to begin with as an LCI, but now it’s a soft and supple ride with 32 PSI all around

I have mine 33/36, and the fucking idrive will not leave me alone about tire pressure, even after I reset it....super annoying to constantly have popups...

From what I've found in my experience with doing the reset it seems to re-set the temp that the system considers "cold" for inflation. So, if I set all my tires in the morning at 60 degrees and do the reset then that's the base for the temps. If it's 80 degrees then the suggested tire pressure in iDrive accounts for that 20 degree delta, and the reverse also seems to be true.
This is all observational mind you; I haven't seen any defined documentation around the behavior.

Well, this thread has been helpful.
I'm gonna say that this has too much nitrogen in the tires.... ...

Today I tried dropping my tyre pressures and what a difference this makes!
I set my pressures at 36 psi round (not cold as I forgot to do this first thing) and it's transformed the ride. To me the car feels less edgey and more settled. The perfect free mod 😁 |
