It has been almost exactly 12 months since I last checked the tire pressures on our RV. Say what !! (The trailer has not moved from its Canadian Covid parking spot in our driveway, since last September) Most of that storage time was with all weight off the tires . . . I don't know if this makes a difference.
All six tires (I carry two spares) . . . five Maxxis and one Westlake were within one psi of 70 psi. They were all at 80 psi a year ago when I parked the trailer. For 12 month, two on the sunny side, two on the shady side and two underneath . . . all retained exactly the same pressure. FWIW . . ."natural pressure loss" appears to be less than 1 psi per month regardless of storage temperature.
Engineers . . . always have to analyze everything . . .
