Side of the General tires says 44PSI max pressure. When I checked the tire pressures on my tandem they were all over the place…low as 32 on one tire and as high as 37 on another. What is the recommended tire pressure (cold) for the trailer tires?
44lb across the board and you are set
I do agree with TAKFishing, I air mine up to the max cold prior to taking my boat out. I also am a firm believer in all wheels being balanced as well.
What does the placard at the tongue of the trailer say? I’d run that recommendation and depending on how the tires are wearing adjust psi up or down slightly. With a tandem axle you shouldn’t need to run max psi as it’ll cause the trailer to not ride as smooth and bounce more, also keep in mind air psi varies approximately 1psi per 10 degrees ambient temp. So if you set them at max in the morning when air is 30* lower than during the day, they’re going to be 3 psi too high in the afternoon.
10% less than max to account for temperature increases throughout the day.
For example my Sabre on a single axle trailer says to set tires to 40psi, their actual max psi is 50 as they’re true trailer tires and at that rating they’ll support 1760lbs each or 3520lbs total. A dual axle is 1570lbs each or 6280lbs total at max psi which I doubt your rig weighs. If your max is 44 then you have passenger tires though can still look at the sidewall for the load specs.
Remove 10%-15% per tire from capacity ratings for a safety factor.

I went to 38psi for each tire as I figured the percentage reduction was needed.
The reduction does not refer to air pressure, max air pressure out. The reduction has to do with a vehicle tire rated at 2000 pounds for a vehicle would then work for a trailer at 1800-1700 pounds.
On trips with the C130 I would have to let tire pressures remain high in Hawaii due to the fact that we were off to Alaska and the temperature difference was around 100 f …. that tends to change things.
The biggest thing is to check the tire pressures regularly and keep them equal . This helps keep the trailer inline while towing.
You would be surprised by how much abuse a good tire can and does take.

Is this for tongue weight as the vehicle should be taking ~10% of the load off?
no, it’s a trailer industry standard when using vehicle tire.
