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.
