I just put new tires on my trailer (open deck) & they are 10 ply, 10". I am wondering if I should run the max pressure on these tires. It says that 90psi is the max. Any thought / opinions?

That would depend on the load rating. The tire should spell out the max weight they can carry. Figure out what half your load weighs and then compare that with the max carry weight of the tire. The closer you are to the max weight, the better chance you will need max pressure. Also, cold weather creates a condition where tires lose their pressure faster. If you check your tires early in the season and they are fine, by late season they may be under inflated if you don't keep up on them. By running a bit more air (yet staying under the max listed) you give yourself a margin of error so that you don't get hot tires and blow one or both out prematurely.
If your trailer has a data plate that tells you how much air to run in the tires, run that amount. Other wise if you plan on hauling heavy, run the max pressure on the sidewall of the tire. You have to figure in the weight of the trailer and cargo..If you are running lighter than the max tire weight per tire you can run a little less air. I would run max air pressure all the time.
Here is both the easiest and best way I have found to find the correct air pressure for any tire...air it up to 10 pds less then max pressure shown on sidewall. run down the road at close to the speed you will be running(with the load you will be hauling)for 5 minutes, then pull over and jump out and lay your hand on each tire..if its cold /cool it has plenty of pressure, if its just luke warm, pressure is correct, and if its too hot to leave your hand on the tread..its low on pressure..add air pressure, slow down or remove load or other wise the tire will destroy it self in short order. this works on wheel bearings too(too hot to hold onto the dust cap means too much load, too tight of bearings, or lack of grease....
