Ryan,
There are a lot of questions in your post and inorder to answer them we need to start with apples to apples comparsions.
First, an ST trailer tire carries considerably more load than a comparably sized passenger car tires (Don't forget to reduce the Passnger car tire load rating by a factor of 1.1)
ST trailer tires are much more like LT tires - and if you compare the prices of ST tires to LT tires, you'll find the ST tires are cheaper.
But part of the problem is that there is very little overlap among these 3 types of tires.
Also, some trailers are used such that any particular tires will "work" - slow speeds, light loads, etc - but if you subject them to types of things passenger car tires are subjected to - eg 80 mph - trailer tires will fail in short order.
