MIL-P-27401 propellant pressurizing agent, Nitrogen, Type 1, grade A.
Type 1 is Gaseous
Grade A is 99.5% pure (grade B is 99.99 and grade C is 99.995)
Water, PPM = 26.3 (70degF, 760mm)
As a cross reference, another Nitrogen spec, A-A-59503 Nitrogen, Technical; Type 1 (gaseous); Grade B (99.5 pure) has moisture content Max 26 PPM.
Your question: Does anyone knows what is the humidity dewpoint admissible in aircrafts tyres?
26 PPM per the above specs.

The manual also states; " Oxygen concentrations should never exceed 5%.
In a Michelin tire clas I took they talked about moisture, but I cannot remember the numbers they called out.
