What should the PSI be in the trailer?

The oem tires call for 110... I would be running 110 minimum.

Why? If you're getting good wear patterns and no issues with running lower pressures why would you blindly follow recommendations that are based on "E" rated ST tires? "G" rated LT/ST tires don't show the "B-Ball" effect, their sidewalls are too stiff for that to happen. There's quite a bit of data that suggests there's no reason to blindly follow the "Use Maximum Pressure" suggestions. Good wear patterns, long life, not beating your trailer to death, all good reasons to run lower pressures on "G" rated tires.

JMO of course, and I will continue to recommend that people with "G" rated tires experiment with air pressure until they find what works best for them.

Hey there is the BLIND way to go thru life using the CYA method or one can actually use their BRAIN and do what is BEST for their situation. I prefer the latter. ;)

Max pressure is CYA. I use the CYA method because I have suffered through the blowouts from the era when I did not use the max. Pressure CYA method.
Again I do not want to derate the tire by not filling it to max. PSI.

BY the way are you filling each tire to a different pressure using those charts? Are you assuming each wheel weighs the same and carries the same/equal load?

You are supposed to weigh each tire if possible and air that axle to the highest weight.

I run MAX on my DRV because I have a HUGE axle load. I run my ENDURANCE tires based on load on my Boat trailer. I run my MAXXIS tires based on load on my MC trailer (ENDURANCE were not available). If I were to run MAX the MC trailer would be bouncing down the road. I inferred all 12 of my tires at every stop and in ALL conditions they are running cool.

Should I rum my DRW's rear tires at 80??? Do you ???

My truck placard says 65 for full load, I run full RAWR so I run 65 as the weight/inflation chart will also tell you.
