A couple of points to make here...

First -- if you're going to run high inflation pressures (I typically do,) be aware that your wheels may have maximum inflation pressures too. Mine are stamped "40 p.s.i. max". I don't exceed that even though my tires will go to 50, I think.

Second, for all you speedy guys towing at 70 or faster, be aware of the speed rating of the trailer tires. If they're rated to 65, you may be pushing things by towing 70 and faster for hundreds of miles. (Yes, I'm guilty of that, too.)

•Trailer tires are not designed to wear out.
•The life of a trailer tire is limited by time and duty cycles.
•The mileage expectation of a trailer tire is 5,000 to 12,000 miles.
•"ST" tires feature materials and construction to meet the higher load requirements and demands of trailering.
•The polyester cords are bigger than they would be for a comparable "P" or "LT" tire.
•The steel cords have a larger diameter and greater tensile strength to meet the additional load requirements.
•"ST" tire rubber compounds contain more chemicals to resist weather and ozone cracking.
•All "ST" tires have a maximum speed rating of 65 mph.
•As heat builds up, the tire's structure starts to disintegrate and weaken.
•The load carrying capacity gradually decreases as the heat and stresses generated by higher speed increases.

Reading that list, I see many things I would not consider "special trailer points" in my case. My trailer, car and tires loaded is only 4600lbs...that's less than my truck so the BS about "heavier construction" means beans to me. That list makes an LT tire sound BETTER for a light weight trailer.

I can understand that list applying to a heavy or heavy duty enclosed trailer pushing the limits of it's axles and getting side loaded from tight turns all the time. Most LT tires are rated at the same amount as a C range tire which is currently on the trailer.

if someone said they were biased ply so they could tolerate long periods of stationary life which is better than a radial that might go out of round, I would buy that before the list mitch quoted from discount...

I am going to look into the place Adam mentioned and see what they have now and report back.
