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.
The air pressure for many tires is 32 pounds. The sidewall of the tire will be stamped with the correct pressure for the tire.

My 2003 4 runner is recommended for 32psi. Check the drivers door jam. On it you will most likely find a sticker telling you the correct tire pressure.

Front/Rear 30/35
The proper pressure for you vehicle's tires will be listed on the label on the driver side door jamb.
