Tire Pressure Actual vs Sticker
Went and weighed my RV today. Sticker for my tires are Michelin: Front Axle: 235/80R22.5G GAWR 8,000 lbs @ 90 PSI Actual weight: 7,700 lbs. 105 PSI Rear Axle Duals: 235/80R22.5G GAWR 15,000 ...

The difference is small enough and the nature of RV tires is such that it likely won't make much difference...
First: you gave the sticker weight, the sticker pressure,
The acutal weight and pressure
You did not give the recommended pressure for that weight (You get that from Mitchiln and be advised that the two ends of an axle may be DIFFERENT.. yup)
The proper pressure or perhaps a few (5) PSI more gives the best control under less than ideal conditions, a good ride and the best tread life.
RV tires almost never run out of tread (They run out of calendar life)
Slightly high si not an issue but I'd likely take 'em down to at least 100, if not 90.
