Your tire pressure thoughts please

2007 Monaco Knight 38PDQ
Tires are Goodyear 275/70R 22.5 6670 RV Load Range H
From the day we purchased the unit new, and when we picked the unit up, the tires were inflated according to the Tire Info Sticker located behind the drivers seat. I realize that this is just a weight to cover what ever the user may load into the unit. I have the coach loaded with about everything you can pack into the unit so I figured I probably have the weight limit maxed out, so just kept the pressures where they were.
Steer Axle: 115lbs
Drive Axle 95lbs
I have had no problems with the ride etc. But had the unit weighted and this is the info from the scale:
Steer Axle: 11,300 lbs
Drive Axle: 18,300 lbs
From the Goodyear Tire Pressure Chart it appears that the following pressures should be used:
Steer Axle: 95 lbs
Drive Axle: 85 lbs

WOW that seems low.

Give me some feed back

I have the same size tires on our 40' CC except they are Michelin. Been going on a merry go round trying to determine the correct pressure. Our steer axle is exactly 12k and that is from four corner weights done by a cop who helped me out. To support 12k Michelin states to inflate to 110psi and the key is that is COLD pressure. I have as TST TPMS system and can monitor not only the pressure but the temperature of each tire. It is not unusual for me to see the fronts get to 120 or slightly above when on the road as shown on the TST monitor. I was told that is within the safe range but it still makes me wonder if the tire is overinflated.

Rather confusing but I thought I would share my thoughts with you.

I go with 5-10 lbs over the chart, the higher if the chart puts it at the low end of the tire's pressure range. Then check the ride/handling and monitor tire wear pattern over time.

I have TPMS as well and see how much the pressures increase when hot - this is normal.

Ditto here. Don't worry about tires appearing over inflated when they're hot. That's built in to their specs.

I was concerned with my 255/70/22.5 michelins as well. This past summer I purchased TST tpms and was alarmed to see the fronts start at 105psi and rise to around 120psi. Guess that is normal but still seems high.

That's just about where we run. Specs on our tires (based on actual 4-corner weight of the MH) say we should run 95psi on the steers, but we run them just around 100. The 95 just seemed a tad too low and the 100 seems the best ride. We have 275/80 tires on our Endeavor.
