By the way, no trailer tire is designed for 65 mph so beware.
All 225/75r15:
Goodyear Marathon 75 MPH (with 10 PSI added).
PowerKing TOWMAX STR II 75 MPH.
Trailer King ST RADIAL 75 MPH.
Carlisle Radial Trail HD 81 MPH.
Carlisle Sport Trail LH 87 MPH.
Hartland ST Radial 87 MPH.
Gladiator QR25-TS 87 MPH.
I'm guessing your belief may come from a false statement on Discount Tire's website: "All "ST" tires have a maximum speed rating of 65 mph. It's simply wrong, and seems to get repeated a lot. Heck, you can find "Speed Rating N" (87 mph) tires listed on their own website.
