Proper tire pressure for PS4S

Angmar · 10-12-2023, 10:07 PM

Guys,

Anyone know what the proper tire pressure is? I was in the settings on my 2024 and noticed the tire type wasn’t setup so I picked summer tires. Now my check tire pressure warning is coming up even though I have around 32-33 psi cold and 35 psi after driving for a few minutes. I believe the car was telling me the back should be something like 46 but that seems really high. I’m pretty sure it recommended 36 in the front as well.

Unless tracking a car, drag racing a car, or hauling a ton of bricks, I've always been told to go with the door placard. So that's what I do, and I've never gotten a warning.

Both the placard and owners manual say 32 psi. I'm running PZeros, but I doubt that would make any difference?

Depends on load. As squid stated, if you are mostly driving alone, aren't carrying a shit ton of bricks, don't actively exceed 100MPH+ 32 is what you should go with.

For my G42 (which I have only had for a few months) the "My BMW" app shows 36 psi all around currently, but the placard says 38 psi.

I have the staggered setup with the PS4S tires.

The app was recommending 39 psi but I changed it to manual/summer (from auto) in the infotainment and now the app isn't recommending a tire pressure.

What are you guys seeing in the app?

My app has never recommended a tire pressure AFAIK (and it isn't doing so right now). It just shows the tire pressure.

I don't know what causes the app to behave differently.

Same here. The app just shows the last tire pressure before I parked the car.

Interesting… I think it was because the tire type was set to “auto” in the infotainment. Set it to “manual / summer” now and not seeing a pressure recommendation in the app anymore.

Also noting I’ve got a G42 and I think this is primarily a G87 thread.
