As Sam suggested, make sure you reset your TPMS.
You guys may have already done this, but it's a good reminder in case you haven't.
I was at the TireRack last Friday and they installed a set of
Bridgestone RE970 AS tires. When I got in to leave the TPMS was lit up,so I just reset it. It only took a few feet for the system to reset. They put the PSI at the recommended door sill numbers, 32ft and 35rr.
I have a 335i Msport with 18" staggered sizing.
Owners manual shows different psi for 328i and 335i even with same size tires. These are normal psi, not high speed high load.
Make sure you're starting with the correct PSI before experimenting, so that you have a good base starting point.
328i RWD and Xdrive with 18" square - 32/35
18" staggered - 32/32
19" staggered - 32/35
335i RWD and Xdrive with 18" square - 32/38
18" staggered - 32/35
19" staggered - 35/38
