Tire pressure recommendations different between iDrive8 and door

kudos · Yesterday, 05:42 PM

The iDrive 8 tire pressure rec says the front should be 44psi and rear 42psi.

The door says front 38psi and rear 42psi.

Which one am I supposed to believe? It's a square setup.

pretty sure the idrive recommendations will change and are based on other variables like air temp

It might take into account type of tire too. Runflat vs performance/summer.

it doesn't matter. Run different numbers for a week at a time and see what you like

Are you tire settings manually set in idrive?
If so, make sure you have "<100mph" set.
