tire pressure - again
I know, I know, this has been brought back more times than the living dead. My question is very simple. My tires on my 16k# coach are Goodyear g670s. I like them. The sticker inside says to run them ...

Effy,
You are correct, but perhaps overthinking this.
Indeed, with change in temperature, tire pressure changes (very little change with change in elevation).
SO, here is my recommendation:
Best-- weigh individual wheel positions and use heavier wheel position on each axle to go to your tire manufacturer's inflation chart. If only axle weights, see *1.
The chart will tell you the MINIMUM PSI for your given weight. Add 5 PSI to that minimum for a small safety margin.
*1 If only axle weights, you must add a fudge factor for side to side imbalance (say 5 PSI) as well as the 5 PSI for a small safety margin (as long as this does not exceed the wheel or tire limits).
And, yes, if you experience a 60 degree temperature swing, you WILL have to adjust tire pressure!
Remember when the tire manufacturers say PSI cold, they mean before driving at current ambient temperature.
