It is refreshing to see that the OP has studied this subject and figured out that the continued recommendation to utilize ST tires is not as good a solution as making the switch to LT rated tires .
Too many posters on this forum seem to " glaze over " with the technical and just plain give up trying to understand that ST tires are made to a lower price point .
ST tires work as long as they are just sitting .
But for hauling trailers in 110 degree temps there is no substitute to swapping out the lighter weight ST tires in favor of the heavier standard LT tires .
