Depends upon the source of their N2 and the condition of their dessicant. If it's a saturated dessicant cartrdige it may actaully give up H20 to the N2 but only if it is well beyond its service life. There are other air separation processes used for low grade tire N2 such as semi-permeable membrane and pressure swing adsorption but they all are pretty darn good dessicating processes too. If the N2 came out of a high pressure cylinder its almost certain the gas was produced by liquifaction and is very dry....<<<100F pressure dew point.
