The new gen high speed rated ST tires like the Provider ST or Carlisle RH and especially the newest from Carlisle HD tires are the way to go if your going with a 15" tire for a 10k gvwr trailer.
The best upgrade for trailers in the 10k -12k range/5.2k-6k axles would be 16" LT tires....if the trailer has 16" wheels.
The Maxxis is a bit dated and we have had several members on this and other websites who had issues with them. Maxxis says not all their ST tire sizes has the nylon cap. I would check with them first to see if your size has the cap if you choose to go that way.
