I think I will add 5 lbs to the chart recommendations and hope for the best!
Do you have any CAT scales you can get to?

CAT Scales in my area can only give you the axle weight not the individual tire.

I dropped the fronts to 100, the drives to 110 and the tag to about 95
Remember these are hot temps
The ride change was amazing.
The storage facility do the preflight on the owners behalf - batteries tyres fridge water etc.

So don't worry about adding a bit more for this and a bit more for that - the charts are accurate and your calcs are correct.
Steve Why would you ever consider changing tire inflation when hot? You should be setting your pressures cold and the cold inflation should be based on the individual tire loading and consulting the chart published by the tire company. You should always set the pressure on all tires on an axle based on the heaviest loaded tire.
Have you provided the storage facility with a spec for the proper tire inflation?

Lower inflation will almost always result is a softer ride. It will also result in more tire killing heat and worse fuel economy. Here is a post with more info on inflation and ride.

Here is a post on inflation in general.

What is the minimum inflation?

Here is a site with good info and even a worksheet you can download to show how to get individual corner weights on a regular axle scale.
