need opinions on tire pressures

Goodyear says on the tires side wall "inflate to 65 psi". No questions about what Goodyear recommends.

I can quote Goodyear, and provide a reference for the quote:

Overinflating can reduce traction, braking ability and handling, as well as result in uneven wear and an uncomfortable ride...The proper air inflation for your tires depends on how much your fully loaded RV or trailer weighs...See load inflation charts...actual air pressure required should be determined based on the actual load on each individual tire.

Inflation pressure should be adjusted to handle the tire carrying the heaviest load, and all tires on the axle should be adjusted to this pressure.

That is all well and good, BUT from my own recent personal experience setting the pressure to those tables is foolish at best.

This spring as part of my states requirement for an inspection I needed to replace one worn out tire during the inspection. The tire tech underinflated the new tire by 10 lbs from the sidewall pressure.

The tech mentioned to me this AFTER he had installed the tire and where my trailer was sitting they would have had to drag a lot of hose out to top it off..

Since my trailer was not loaded for a trip I figured that that pressure was fine as is (no food, clothing water or personal stuff, pretty much empty of any added weight).

Driving home 18 miles at max of 45 MPH that tire was nearly hot enough to burn your hand if you left it on for a few seconds compared to the other three that were barely warm..

HEAT KILLS TIRES..

Yeah, inflating to a chart is fools game, go ahead and do it if you think you know better.. But for me, I will inflate my trailer tires to the max sidewall pressure, I KNOW my tires are running as cool as possible.
