Tire pressure and temperature recommendations

Remember if you have been driving, pull in to weigh your snot, and adjust the pressure, next morning, when your tires are the same temp as outside air, you are setting on underinflated tires. Within a hour you might be setting alongside the road

Correct!

Proper order is:

Get weight ticket

From your tire manufacturer's Inflation Table, determine proper minimum PSI based on axle weights. Add 10-15% as a safety cushion-- perhaps 15-20%, as you need to account for left/right imbalance.

ONLY adjust PSI before driving more than a mile or two and better in the morning (after sitting overnight) as ambient temperatures are lower and you need to be able to have correct PSI when you start out in the morning.

I run what the MH manufacturer recommends on the VIN/GVWR tag. Have never had a problem. I have had each axle weighed and that had the same result for the pressure recommended.

Good advice IF (yes, the bad) you are near the GAWR's for your coach.

Said another way, if you are well under GAWR's/have a healthy weight safety reserve, you are over-inflated.

First leg of trip is done. Had 10 miles of interstate, so no chance to get weighed. The plate in the cockpit says 95 for rear and 105 for front. So that’s what I went with.
By the time we got here, they were all around 118.
Does that sound okay?

Until you get it weighed, yes follow posted PSI on the GVWR plaque. Hopefully that will end up being over-inflated, indicating you have some weight safety reserve and actual weight is less than GAWR's.

105 to 118 is about right. Temps will increase depending on road conditions, air temp and your speed. 10-15PSI increase is ok....Dennis

It’s my understanding that the temperature feature is not intended to warn you about high temps per se but rather to give you the second part of the needed equation to give you a better understanding of the pressure readings.

As the tires heat up the pressure goes up also. Without knowing the temperature a pressure reading while rolling down the highway after a few hours of driving of very hard to relate to ‘cold’ readings.
