I can't say enough good things about Goodyear's Endurance trailer tires. Unfortunately they don't have them in your size but they are just about the best tires available right now. Maybe you could go up one size to the 205/75R14 but that would mean replacing the wheels as well and would also need to check for clearance under your rig. It would also increase your load rating to 1820 lbs which would give you that little extra insurance. Check the loaded weight of your trailer. Sometimes the OEMs put the closest to max capacity or even a little below. My original China bombs (Constancy) were just under the trailer's max. With the same size Endurance (I have 14"), I went up a load rating and have that extra even though I don't ever go over the trailer's max load rating.
Carlisle are OK but I've seen some of their tires be really out of balance and out of round, mostly on their smaller sizes.
