"Unless trying to resolve poor ride quality problems with an RV trailer, it is recommended that trailer tires be inflated to the pressure indicated on the sidewall of the tire. Trailer tires experience significant lateral (side-to-side) loads due to vehicle sway from uneven roads or passing vehicles. Using the inflation pressure engraved on the sidewall will provide optimum load carrying capacity and minimize heat build-up."
Your going to upgrade tires and wheels so use use all of the tires reserve capacities instead of the minimum amount.
I'm not in disagreement with what you're saying here. I make the post about what Maxxis says as information. They are the only ST tire manufacturer I know of that supports any pressures lower than full sidewall pressures.

I hear you. Thats where a knowledgeable tire dealer can step in and save the customer some grief and bucks down the road.

They may also be the only manufacuturer of a ST235/80R16E that makes a tire that weights in at more than 35 lbs. At 43.43 pounds maybe they do not need the bandaid of full sidewall air to live on larger trailers?

Running the E rated Maxxis at 65 psi didn't really gain anything over the D range tires they replaced, which were probably already maxed out or overloaded. In order to have gotten some benefit out of the investment, the OP would have needed at least 70 psi, with 75 to 80 psi preferable. However, in the OP's case, the wheel was not rated for the higher pressure. I have been led to believe that the odds of a rim failure from overpressure is higher with the aluminum rims like the OP has than with a steel rim.
The prescribed path makes some sense. Have the running gear checked by a professional, get the weights, and replace/adjust the equipment as necessary to handle the conditions.

Well, we made it home today with out incident. My eyes were glued to the mirrors watching tires all the way back down from Flag to Tempe. About 60 miles south of flag I pulled off at a rest stop and shot tire temps. The 2 Green balls (Passenger side) showed 104-105. Drivers side which was the sun side, Goodyear Marathon 105, Maxxis 110. Any one know how hot is to hot for tires?. Now I just need to find the time to get it weighed, alignment checked.

I would get concerned at 130-140 degrees that something was wrong. My XPS RIBs run in the 115-120 range in hot SW weather.

When I ran Marathons, they ran in the 115-120 range. Just got back from a trip with the new Commercial TAs and they also run at 115-120. I'm running them at 75 psi.
I checked my individual wheel weights before I left. Both on the street side were 2350. Curb side rear was 2750 and curb side front was 2700. I was overloading the Marathons on that side.

"Crossfall camber" will cause those right side tires to get warmer than the left side.

I've ran Maxxis LTS since about 03. Never lost any until this year. Lippert came to do some axle corrections. The service man only moved one axle which we did not know until last winter. One of my Maxxis tires had very slight wear on one side. Took to dealer and the lippert problem was discovered. Had to rebuild everything back to correct specs. dealer got the correct specs from Mor Ride. Heading to Colorado we were flagged down by a kind person in a small Oklahoma town. Only 60 miles from home. The Maxxis that had the slight wear was losing the tread, however, we thought there might have been a small nail. anyway Maxxis LTs have been very good to me. Also proper air, and proper highway speeds. I'm sure the Texas Oklahoma heat this year did not help the tire at all.
