I thought STs had thicker sidewalls and thinner treads.

I stumbled on my mistake in my earlier post with this quote and so forgot to answer your wonderings.
Probably there is some difference between built of ST and LT tires, but this does not influence the way they calculate the maximum load for it.
This also is pretty standardized , as CW the mann writes.
Thicker sidewalls for instance would make the tire stiffer and so gives smaller surfacelength , so surface on the ground, with the same deflection, because the overgoing curve from the outside radius of tire to flat on the ground is larger.
So this would only mean lower maximum load and not higher.
Thinner treaths I wonder if they do that to ST tires. Sooner more profile and an off-road kind of profile, with profile-blocks that have more distrance between them and cover a part of the sidewall, witch makes this sidewall less deflection allowed to prefent damage by driving.
Mayby this is the reason why, together with overloading, ST tires often fail.
