What psi do you guys run your tires at? My dealer had them at 45, lol. Seems a little high.

Holy shit! Fred Flintstone tires anyone.

Look under vehicle info in iDrive, it'll give you the recommended pressure depending upon speed.

Which car/model do you drive?

Check the placard in the door jamb. Mine says 41 on 20” wheels (for up to 3 people on board)

My door jamb sticker reads higher, too, than the iDrive recommended settings. Based on experience, I follow iDrive because it feels better.

41psi on my tires turns my car into an E63S (sorry, AMG, but it's true)... and I don't mean that in a good way.

[Jo-Sta07]

32-35 PSI ideally.

Weird - mine says 31/32 but I run them at 33/35 usually. Super OCD about it as well and not sure why I am.

[GranitM5]

I do 35 all around

[jw3571]

Thanks guys. Mine is a 2020 Competition with the 20 inch rims. 33/35 or 35 all around seems to make sense.

I run 35/36 psi for going >100 mph (that's what's stated in the manual for 20 inch tires).

[Higgs Boson]

35 all around and if they get too high when hot I set them to 35 hot (rather than cold).

[weingarm]

Mine were at 36psi all around until the tire pressure set-point got fixed with the rear-view camera recall (it always recommended about 40psi, way too high!)

After the rear-view camera recall I now run 32psi cold all around (it recommends 33 usually when I start it up). PSI rises with temp - I'm usually around 35 or 36psi all around by the time tire temps rise above 70 degrees.

Didn’t want to start another thread. Are there AS or snow tires for the 20” oem wheels you recommend for winter or do you change wheels too?

It's next to impossible trying to find 275/35 and 285/35 20" winter tires. The BMW recommended winter wheels and tires (705M) are too pricey imo (don't see the point in spending that money on winters) so I got some 19" aftermarket rims and Michelin x-ice xi3 (245/45 square) gets the job done. The 245/45 footprint is very close to the summer tires' footprint so your speedometer won't be affected.

i run the michelin pilot alpin pa4 with the same sizes as my summer Ps4s 275 front and 285 back. done it at a BMW dealership.

[F90M5C]

i have been running the recommended pressure by the Idrive which is 3 bar (43 psi) which is way to high. now i run 2.7 bar (39) as recommended by the door jamb sticker and the car doesn't like it and throws the check tire pressure warning all the time, i wonder what will happen if i go with what you guys are running 34-35 psi. should i have 34- 35 with 20'' ?

[soopa]

36/37 cold. I tried lower and didn't like it

Lower it then reset the TPMSs under vehicle info in iDrive. Now you've told the car what normal is.

i did that 3 times and after i shut off the car and start it again after a while i get check tire pressure notification again . but if i put it at 3 bar as the car advises it doesn't come on again

What speed do you have the car's tire settings at?

[MDJAK]

Appreciate the replies above re winter tires. Are there AS tires in the 20” size? I know tirerack doesn’t lost any. I did find some in another site but the load rating wasn’t the same. Not sure how much that matters if it’s close and I’m not loading up the vehicle.

It will need a software update from BMW to correct this.
