The correct air pressure for your 2003 Road King standard tire is 18 pounds. The tire air pressure is dependent upon the type of tire.
Look in the owners manual.
40 lbs front and rear
Everybody prefers their own weight, somewhere between 32 and 40, but I prefer 36, front and back
Typically the air pressure for a road king or touring bike is 40 PSI look on the tire itself and it will give a recommended tie pressure. Ride Safe
