Upgrade to 16" wheels ,seek opinions for tires (LT vs ST?)

I did the switch back in 09 with a 07 Jayco. New Dexstar rims & 235/85 BFG's. Took those BFG's off in late 11 and put them on the Montana for 2 more years. On the light trailers the Duravis & Ribs are overkill. Yes they are better tires. I now run the Duravis. But with the Jayco 70 psi was the max pressure I could run and still maintain contact across the tread. Poly cord tires will be fine, and it is worth the $$$.
