Highly recommend this product line, America's tire had them in 2 days
for about $70/side installed:

Main short term advantage of the *of the "T" rated tire is stiffer
sidewalls=less sway, which will enable higher speeds. *Long term, much
greater life and less chance of deformation and degradation which can
lead to blowouts.

There is a 195/75/15 which is close to your needs, plus others in the
Greenball II line. *I did not see a radial in your size, but note that
Bias will last and has stiffer sidewalls, although it might ride
rougher. *My instruments incuding a Sage have survived just fine.

Check out the excellent calculators on the Tire Rack to get the actual
dimensions. *You can also get the tires shaved at a quality shop if
they are a little big, but I doubt you will need to.

Just like in cars, the right trailer tires can make a big difference
in handling. *My setup ('95 Integra GS-R/SA box trailer, 2600lbs each)
is stable at 70 with only 8% on the tongue, and I get 22mpg at 55 mph
with the trailer tires at 50 psi. *With the "P" tires, anything over
60 was marginal at best. The tires I have now (Greenball II,
ST205/65D14) are 8 YO with no sign of wear or degradation.

Be careful here, even covered up tires in desert conditions will
detariate from the ultra violet rays of the sun in only a few years.
I fly straight out cross country and put considerable miles on my
trailer/tires and you are right trailer tires do much better.
However after 4 years I just replace them anyway ( and usually they
still look good). Nothing worst than a blowout in the middle of the
toolies, which happened to my straight out partner and good friend,
yep on Hwy 50 "the loneliest hwy in America" right in the middle of
it. He too thought that his 6 or 8 year old tires were ok.

I always park in the same orientation, and compare the north tire with
the south facing one. I also note leak rates which can be an early
sign of hidden damage. No doubt, most trailer tires will rot before
they wear out, so vigilance is important.

A good trailer tire will have special compounds in it to resist UV and
standing for long periods. In my case I can see a greenish stain
under the tires on hard surfaces. There are also more plies in the
sidewall of a ST tire than a P tire, or a bias tire than a radial,
another reason I choose bias. Most of the glider trailers I have seen
do NOT have ST rated tires on them, and all the failures I have seen/
heard of have been "P" tires that were either very old and/or showing
cracks in the sidewalls.

I think it is very unlikely any tire would fail under a steady state
condition without some type of visible damage. Despite that they
should be age limited, I think 8 years might be a max limit here in
the southwest. Probably a good idea to jack up the trailer at the
start of the season and check both sides of the tire for bulges and
hairline cracks under max inflation. I do that anyways to check/
adjust the brakes.

Actually, I mispoke earlier on the age of the tires have now. I have
5.5 years on the tires, I will replace them regardless next season as
I choose not to carry a spare.
