Tire Load/Inflation Calculation
Exactly three years ago I bought new tires for my Jayco 23' (27'OAL). I had previously had the trailer professionally weighed at an Escapee's weigh station where they weigh the load on each tire. Unfo...

If you have a TPMS, you might want to try an experiment. Wait for a hot Summer day with the sun beating down on the pavement. Watch what happens to the tire pressures when you start out at the cold pressure corresponding to the maximum load rating. After the tires cool, try the same experiment starting out at the maximum inflation pressure. You will likely see the roughly the same final operating pressure and may even see operating pressures higher for the tires that started out with lower pressure.
I don't use my TPMS much because it's not a very good unit, but the data is fascinating when it's actually working. It's surprising to me that the PSI is so much higher on the sunny side of the rig than the shady side.
