The recommended tire pressures on the idrive system and those listed on the door jam are extremely discordant and not to mention ever changing on the idrive system. BMW NA technical support couldn’t give me a good answer.
I have the 21” all season run flat option.
Door jam lists pressure as 32 psi front 38 rear
Idrive screen varies between 40-43 psi front 45-50 psi rear
What gives?
