Hummm. Does not apply to this car I am afraid. BMW design is such that tyre pressures would have little impact if any. Along with all BMWs the engineers have designed the vehicles as much as they have 50/50 weight distribution, so tyre pressures will have little or no impact. They have even put the battery in the front to get the C of G in the centre for the X1, whereas in many other series they have put the battery in the boot (trunk) to balance the car.

My understanding is that F48 has a 54/46 weight distribution (not 50/50 like BMW sedans). I understand also that even the X drive is also slightly front bias hence the reason why tyre pressure is different from front to rear.
