If you don't know the weights you can be safe by running the max pressure listed on the tire.

You can go to the Goodyear web site and see their tire loading inflation chart, recommended tire pressure vs weight on the tire. But as noted, you need to weigh each axle, and preferably each tire, to see just what the correct pressure should be. Max pressure will ride harder. And will cause more wear in the center of the tread if it is too much pressure for the weight. But is a safe bet without knowing weight.

Besides wear, is TRACTION, as in braking, run the correct pressure for the load. That is not always MAX on sidewall, that exactly that the Maxpressure allowed in the tire.

Improper tire inflation can cause problems for tires.
Underinflating your tires can cause poor handling, fast and/or rregular wear, decreased fuel economy and permanent structural damage to the tire.
Overinflating can reduce traction, braking ability and handling, as well as result in uneven wear and an uncomfortable ride.
• Inflation pressure should be adjusted to the tire carrying the heaviest load, and all tires on the axle should have the same inflation pressure.

Max pressure. While in Elkhart I talked to the main tire supplier there and I asked this same question. They said trailer tires should always be at max and if you have a blowout and request warranty coverage and you tell them you run it below max pressure they will deny the claim.

That is because trailer manufactures always put a minimum tire on trailers. What I mean by that is the tire is carrying right at or just under the maximum weight the tire is rated to carry! Once you chose to upgrade the tires to a much higher capacity, then things change. There isn't a tire on my whole rig that runs at max pressure. I value traction too much to do that. You might try the tape test across the tread. I'm

Special Considerations
"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".
............................................................
Lets assume the trailer is a tandem axle unit.
Most folks that have been around for awhile and have towed trailers for hundreds of thousands of miles know and understand the benefits of max sidewall pressures. We also know we don't have any braking issues nor do we have wearing the tires centers when we have over 3000 lb load per tire.
Now if the trailer is a 16k lb tri axle and you have seriously over tired the trailer with a 3750 lb rated tire then max pressures will be too much pressure. If thats the case then these folks have some good advice;

Tire Load and Inflation Ratings
Note: Towable – Travel Trailer/ 5th Wheel owners Due to the severe use conditions experienced by tires when axles are very close together – tire industry experts recommend maximum (sidewall) inflation pressure for towable tires unless this causes a sever over-inflation situation (20psi+), often referred to as the ‘basketball effect’. If this is your situation allow a 10 – 15psi safety margin above the minimum required inflation pressure.
