But there is a hell of a lot of difference in what you are pulling, and what the OP is pulling.
If I were pulling what you are pulling, I'd like to have XPS ribs also.
But the OP is pulling roughly what I'm pulling, a 4950 GVWR TT. The ST tires I have, ST205/75R Maxxis, provide me with about a 25% margin of error. I feel I'm good as long as I don't run them under inflated, or sustained speeds at over 65 mph.
The OP shouldn't need E rated tires for his trailer.

ST Tires might get you 20 to 30,000 miles but thats not enough for me. I've been RVing for over 30 years and I would run nothing less than Michelin XPS RIB tires on my 41 foot 5ver. I have almost 60,000 miles on them and still have probably another 20,000 or so left on the tread. The good thing about these tires are they are re-groovable which means at least another 10,000 miles. They are 14 ply sidewall and made from the same rubber compound as over the road commercial truck tires. They are not cheap but after buying 3 sets of ST tires which might get you this kind of mileage combined you actually come out cheaper buying the Michelin tires. Thats just my opinion but if your gonna invest in a nice RV then don't go cheap on the tires that you depend on to get you where your going.
