"ST" tires feature materials and construction to meet the higher load requirements and demands of trailering.

"Trailers will be more stable and pull better on tires designed specifically for trailer use. Since Special Trailer (ST) tires are constructed with heavier duty materials, they are tougher than typical passenger vehicle tires."

There is NO independant tests that would verify any of it.
The govt. required ST tire test standards are vastly more lenient than the LT tire tests.
The second problem is that many of the so called special construction is also CHEAPER to manufacture.
