Big issue for me is that there are no major well known tire companies making ST tires except Goodyear with their Marathon. Goodyear moved production of that tire to China and the quality went down. Most ST tires are made in China by manufactures few would recognize. The only ST thats often recommended here would be Maxxis. A 2nd possibly might be Carlisle. They have a long history of having a horribly bad tire. However, they came out with a newer design about 3 years ago that many say is decent. In otherwords, my issue isn't ST vs LT. Its manufacture and consumer experiences for me.
I admittedly don't know much about this topic other than to say that if you have the money and have chosen a manufacturer, go with the highest weight rating you can afford. Reason is they will run cooler and there will be less stress on them, thus reducing the chance of a blowout.
As for Carlisle, I never knew them until I bought a cargo mate trailer that had them on it in 2008. I obviously didn't know what I was doing when I ended up pulling 15,000 lbs with my 1/2 ton from MO to TX. When you pretty much have to tap the brakes to be able to steer, you know you need to start reading stuff. lol My axles were 3,750 and the tires are rated about 2,000 each (I think). I had no issues. Now, the trailer has made a few trips since, but mostly sat in the same spot for years. I had to move it recently and it was obvious the tires were dry rotting. My tire guy said he wouldn't risk it. I bought a spare just in case and took the trailer 200 miles with no issues. A year later (2015), I did that 200 mile trip again. I blew a tire within 5 miles of home because of a construction area that was rougher than a washboarded dirt road. The tire lost its tread, but held together. It was the rear of 2 axles and caused NO damage to the trailer. I know who I'll buy tires from when I have to move the trailer again or when my 5th wheel needs new ones.
Also, I've heard of people filling their tires with Nitrogen as it stays cooler under high heat conditions.
