36lb for the front tire and 40lb for the 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
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.
38 front and 44 rear
40 lbs front and rear

Perhaps when the word "Harley" is spelled correctly - the answer may be provided.
The air in the tire is becoming heated due to the tires friction on the road surface. Heated air increases the pressure in the tire
the tire pressure is on the right side of the front frame behind the forks as you sit on it as you are driving and I use nitrogen in my tires that keeps the tire pressure at a steady air pressure do to heat from the sun and the road temperatures in front and back , should be 30 for the front and 40 in the rear.
I might be wrong but on a Suzuki king quad the tire pressure should be 36 psi!
When a tire runs on the road friction makes it hot, then air pressure increases.
