I fill 33 in front and 41 in the rear as per readings on the door jamb. The pressure on right front falls to 29 in few days and it stays the same. It is xdrive40 with 19 inch wheels and has Bridgestone Alenza. All other tires remains same. I have never used a run flat and when I checked the nearest Tyre shop they said it may not be puncture
