I run LT's and have for several years. I make near 90 degree turns quite often, since I seem to have great luck in camp sites and general navigation snafus. Neither tire, not suspension has failed me yet.
No offense, but it seems that there is a tenancy to over analyze when it comes to this. The way I look at it, the ST's I could find locally kept blowing up, no matter how diligent I was at checking pressure. I was done wasting money on them. I bought new wheels (trailer had 15's) and 4 LT tires and haven't had a single tire problem in 4 years. I believe that vehicle tires are built too much higher standards than trailer tires.
Do it, be done with it and forget it!
Ditto. Other than the EARLY (2004 vintage) LT235/85R16G Goodyear G614 RST (a trailer only tire) which had a known tread separation problem, I've never failed an LT tire on any of our 5th wheels. STs - that's another matter. The scuffing in sharp turns insofar as STs versus LTs is concerned is really a non-issue.
Put the best tire you can get under your 5th wheel - life will be so much easier. The incremental cost of the LT tires will almost certainly be less than the repair bill to fix the damage caused by an ST tire failure, not to mention the stress and downtime.
I've run 4805 lb rated 17.5" tires (Michelin XTA and Goodyear G114) on the last 2 5th wheels and never had a problem.
