In my fifth year with the same coach, (make, model and year) plus my weights are also about the same. Our problem is we have more load capacity in the tires than what the axles can sustain and our weights are off the low end of the pressure charts.
I played with pressures, never going below 80 PSI placard pressure, the first month I owned the coach with new tires installed. Above 95 or so the coach tracked poorly and was all over the road. Plus the ride was very harsh as pressures climbed above 90 PSI. Dropped to 85 all around and have been rolling at this pressure for a bit over 30,000 miles. Coach tracks and handles well. No unusual wear patterns, sidewall cracks or tire failures. Heat checks with an IR none contract thermometer show about 10 degrees above air temp. Rolling on Kelly KSR 245/70R 19.5 tires.
