I went through this research last year when replacing the tires on my "vintage" trailer that I had been running repro vintage car tires on. After much reading of all the debates on this site, and reading owner reviews on many others, I ordered the Kumho trailer tires. I was very happy with them last year on a long distance trip. No problems. They are listed as ST tires on the Tire Rack site but when they arrived they were labeled LT. I questioned that but was told that they are trailer service. I wanted the high speed rating that they offered. I run at 65 often as the trailer is small, like yours. I would recommend the Kumhos.
