Agree with Larry. A trailer unlike the tow vehicle can have too much tire. The Rockwood is a ultra lite trailer and all show a 6k-7k GVWRs.
You didn't tell us what the trailers GVWR was or axle GAWRs but looking at '13 Rockwood web shows the biggest at a 7800 GVWR with a 1380 CCC figures about 1600 lbs per tire. Now add 15 percent for a nice capacity reserves and the the 205/75-15 C at 1820 lb work out fine.
Higher pressure 65 psi tires require higher 65 psi pressure rated wheels. You want to run the ST tire at its max pressures so the wheel will need to be be rated to use 65 psi. Some 15" wheels are rated to 50 or 65 or 75 and 80 psi.
No more than your trailer is on the road I would go with the 205/75-15 C at 50 psi. Brand is your choice as IMO a ST tire is still a ST tire and all brands have the same issues. Even the Maxxis ST8008 although they seem very popular at this time.
Or the new and improved Carlisle RH may actually be improved.
