Don't understand why dealers are stating lower PSI's? I would have thought the manual and the same reading on the door would be the correct PSI?

These lower psi seem to be from countries outside of North America.
So are you running 38/45? Any premature wear on the Contis, and how many miles?
FWIW: Here is the M50i psi recommendations (full load) under 100 mph. There's nothing noted for light loads however:
