I got a tip to look for LT23585R16 tires, that declare the entire UTQG code, not just load range. When you look, you will find VERY FEW that do. A friend told me that he has had excellent luck with Hankook DynaPro HT. Guess what, they show temp of A. I'm going with those, or Mastercraft Courser R/D, also temp A. The replacement interval on trailer tires has been well documented, but knowing the temp rating can't hurt.
