I noticed on my last trip the MH handeled very well when the TPMS showed the hot pressure at 66-69 across the range of 6 tires. My pump was showing the pressure at 60psi when cold inflated, but the TPMS showed 55. Winnebago recomends 65, but the loading charts for the tires show a huge margin of safety at actual weights at the scale. I thnk the issue with mine is that it is a shorty at 27', and I surmise the pressure of 65 is for the entire Sightseer line. My gage, the tire pump and my TPMS all give different readings.
Actually the improvement in handling at these pressures was nothing short of remarkble. I felt noticably less fatigued. I don't remember the tire temperature, but the alarm didn't go off. I'll check that next trip.
