We have purchased a new 2014 model year trailer from a private party (they bought it new in Oct). It is a triple axle with 225 75 15 Tow Masters not sure if they are D or E but it doesn't matter because they are not staying on the unit. The axles are 33" spaced so they have room for a 16" with 225 75 16.

I have also considered the Maxxis LRE in the stock size but after the bad luck I have had with ST tires I really want to put some Duravis R250s on this thing and never worry about it.

Is my only concern the clearance to the underside of the trailer?
Will the larger tires impact turning, deflection of tires, or anything I have not even considered with the triple axle?

I would check the construction note on the side wall. If the tires have been manufactured with the nylon cap over the steel belts that is an indicator that they are the new construction. The construction note, load range E and being manufactured 2010 or after would indicate that you might have some good tires. If all of these metrics line up, I would take it to the scales loaded and do complete loads study. Three axels and load range E tires you might be ok. I ran Ameritrac made by Unicon tire for four years without an issue. You can't judge today's ST tires based on the old construction reports. Times have moved on.

The original tires were d rated 15" st. They had the stamped weight capacity but we all know that is a "yeah sure" number designed to make you feel good as they go boom. The new r250 16" are on and look and ride great. Amazingly the old 15" rims were not even rated for an amount equal to or above the tires!
