I have staggered 20” on my car, and have them set at 36psi all round for normal driving, and has worked perfectly well for me. If I have anyone in the back AND luggage I go up to 40psi at the rear.

Yours is a 740d X Drive, it might have different recommended settings from my 730d rwd. Do you know what the door sticker suggests for your car?

I don’t think it does, as the sticker covers all wheel and tyre sizes from 17” to 21”.
Here is mine. Hope that helps

In some markets...BMW has limited the amount of info on the door sticker...so its best to turn to your owners manual where it should list tire inflation levels for multiple models, number of passengers, is the tire size on the front or rear, & speed.

The front 20” tires would be a 245/40/20 tire with a Y speed rating...the chart says with up to 3 people the recommended PSI should be 35. If he is carrying up to 5 people...then the front tires should be inflated to 38 PSI. The 20” rear tires in a staggered set up would be 275/35/20...the chart says that tire in the rear should be inflated to 35 PSI with up to 3 passengers...but should be inflated to 42 PSI if carrying 5 passengers. Using the chart you have to determine:

This post is fantastic , I have been putting the incorrect pressures in my car since I got it. I didn’t read the chart properly , I had been running 32 F and 35 rear and recently switched to 35 F 38 R . But after reading this thread it should be F 35 and R 35 . It now seems logical and clear . Thank you .
