Correct tire pressure?

[JBJB]

Hi, anyone know the correct tire pressure for 2012 528i M-Sport using stock tires?1. My SA told me 34 psi for both front and back2. The pre-inspection report said F - 2.2 BAR (32 psi) and R - 2.4 BAR (35 psi)3. The door label says F - 2.3 BAR (33 psi) and R - 2.2 BAR (32 psi)What are you guys using?

What are the stock rims & tyre sizes bro?

Front: 245/45 R 18
Rear: 275/40 R 18

Front: 245/45 R 18
Rear: 275/40 R 18

Same size as my E39. I'm putting 36 front 38 rear. But my E39 weighs about 4000lbs (1795kg), different from your F10 though.

I would Always follow the door label. There should be 2 on the door label too. One is for partial load, and one full load.

Indeed there is 2 different pressure for partial load and full load. This is a pic of my door label:

If I'm reading correctly, for full load F = 2.5 BAR, R = 2.7 BAR.

I am on the similar tyre profile. Usually drives alone but sometimes with full load ( 2 adults + 3 kids)
I am currently on 230 kpi (front) and 250 kpi (rear). I find it adequate.:wink:

Wanted to ask, do you guys change the tire pressure up/down depending on the load?

From the door label I posted above, there is quite a bit of variance between normal and full load. Thinking if I can go mid-way to avoid worrying about the tire pressure when suddenly got full load.

260 kPA all round.
makes the car zip quicker.
