Using max pressure will reduce any sway, and more importantly give a reserve capacity... This can be important. If on tire blows on a tandem axle for some reason, the remaining tire takes it's load. If running reduced pressure, or tires that are right to the limit, it means that the remaining tire should be replaced as well as the blown tire, as it was likely damaged due to being overloaded.
Most of the time max PSI is used on trailer tires because most trailers are towed near gross weight.
Sometimes trailers do not weigh close to the gross weight and your tires may wear out in the middle at max PSI. So, over time, check the wear of your tires and its ok to reduce the PSI by 5 lbs or so in order to have your tires wear correctly.
