Biggest thing I can suggest to anyone, no matter what brand, is to get a load rating with as much reserve capacity as possible. Many many of the tire failure stories I read here have a common theme of being close to the rating.
My ST 205 75r14 load C tires are rated at 1760 each x4 = 7040lbs My trailer is about 5200 loaded with about 700lb tongue weight, so travel weight is 4500-4600lbs. That is A LOT of reserve, and I have not had a failure that was not road hazard or age on the basic towmaster type tires I use.
