TT tire upgrade, should I go with Loadstar

Let me add from my original post, my tires are 205-75R-15. I failed to mention the rim diameter. Unlike most of you, I won't be pulling the trailer more than a couple of times a year. We are in KY and we will initially pull it about 900 miles to Florida where we will store it. Then a couple of times a year we'll drive down and hook to it and take it to an RV park somewhere in Florida, likely within 150 miles of the storage location. We plan to stay in it for a month to 6 weeks each time. The tires won't see more than 600 miles a year after we take it to Florida. Whatever tire I put on will likely dry rot before they wear out.

Thanks for the advice so far.
