If you can find the specs on your tire pressure gauges, check them and you will find the accuracy specs can vary significantly. On top of that, drop a gauge just once and its a whole new ballgame. An accuracy of +/-10% is not uncommon with inexpensive gauges. Using that, 65 psi could be anywhere from 58.5 PSI to 71.5 PSI. The only way to be able trust a gauge, is to buy a quality one, test it periodically against a known accurate one and take very good care of it.
