I forget, I am running something like 205-70-14's on my travel trailer. I do 55 to 58 mph, and always top off the pressure to 55 psi as stated in the instructions. I am at 14,000 miles in 2 years of ownership. So far, so good, but I am checking the tires like a hawk now, every time, before every trip, for signs of delamination.
Maybe this isn't such a problem with 3700 # dry weight ultralite travel trailers?
I followed all those same precautions you are doing with my two previous trailers with ST tires and had blowouts after the third year. The tires looked great until they came apart on the hot highway.
I believe Discount Tire even tells you on their web site that 3 years is the the expected life time for STs.
Someone mentioned the improved Carlisle tire with a nylon cap so maybe the new ST tires will hold up better. I switched over to LTs 7 years ago when we got a new trailer with 15 inch wheels and have not had any more problems.

Towmax STR also has a nylon cap.
