Why are so many hot shot/car haulers running smaller LT tires?

I'm curious if anybody can answer this. Down here in Texas, I'm noticing that the majority of the wedge car haulers with dually axles are running LT truck tires on their trailers. I run only 235/80/16ST tires on all my light trailers unless 235/85/16ST are needed for running a heavier axle single wheel application. While mingling with other drivers at auctions and such, I keep getting the answer that ST tires are giving everybody problems with blowing out, this is news to me, but I only drive around Texas.

To summarize, if you are running a car hauler or hotshot rig, are you running ST or LT tires and why?

I find it difficult to reduce size to something like a 245/75/16 when I already have ground clearance issues. I grew up knowing that Trailer Tires go on Trailers, and Truck Tires go on Trucks. What is going on here?

I just ordered a new set of Hartland 235/80/16ST at $120/ea for my 50ft Kaufman Wedge with tandem 10k oil bath axles, which is why this question has popped into my head. LT tires do not seem to have near enough weight rating, and I like to have beefy tires compared to the axles. I do not enjoy changing china bombs on the side of an interstate when fully loaded.

Thanks kindly.

 

Fair Enough,

I try not to judge, but it just blows my mind that so many people are running LT tires. I am curious if anybody here that is running them will chime in with something. Having good rubber on the blacktop is one place I will not compromise. I might not buy top brand tires, but I don't buy the cheapest by any means.
