Goodyear Endurance Tire Pressure
Recently, I had 4 E rated Goodyear Endurance tires mounted on my 5th Wheel to replace the less than stellar Castle Rock Chinese tires that were on my camper originally. My EEZ TPMS showed Three tires ...

If you really want to end this business; drain and fill the tires with nitrogen 3X's. That will stop all of this.
Nitrogen is a scam
OP, what does your high quality tire pressure gauge read in comparison to your TPMS read out? that will tell you what pressures you need to know.
I have no idea what Nitrogen 3X is, but if it's being sold as a tire solution it's a scam.
One of the common statements supporting N, is water vapor in air. Most (all?) tire shop air lines go through a water separator filter. Is it completely dry, no, but it's dry enough. Tire temperature would have to get deep into 200°F to "boil" the water vapor. If you're tire is 250°F, you're already in deep doodoo.
water seperator filter does nothing but keep the RH of the water to below 100%. They typically don't desicate to 0% RH. Once inside the tire water can condense or vaporise depending on temperature and once vaporized have an increased effect on tire pressure. regardless of temperature once above 32F, water will vaporize till either it is all vaporised or RH-100%. That adds another variable in the pressure due to added vapor.
Now all that, IMHO for typical consumer use, it really doesn't make enough difference to even care about. If your application is racing or other things where small changes in tire pressure have a big effect, then dry air is important.
