Tire and Wheel Woes

Background: We threw tread on our 2013 Cardinal 3675RT, Goodyear Marathon ST235 80R16, and are now shopping for new tires. The RV weighs up to 15,000 lb loaded, so here are my questions:
1. We like the Michelin XPS RIBs; however, they are rated at 3,042 lb per tire (12,168 lb total). Hence, not good.
2. We also like the Goodyear G614 with the 14-ply; however, it takes 110 psi and the original RV tires took 80 psi. Hence, we believe that the rims may not be stout enough to handle the higher pressure.
Is there any definitive way to determine the pressure capacity of the original rims? They are stamped with maximum load, and several other notations, but I cannot find on the Internet what these designations mean.
Am I destined to buy new wheels too? All help is appreciated.

For what is worth...Our Sabre tires are rated max cold psi @80 psi...When I took one of the factory rims off, stamped on the inside rim stated 100 psi capacity...If your rims don't indicate a max psi rating, then aftermarket wheels would be recommended

The Michelins may still work. What is your pin weight? The tires need to carry the trailer weight less the pin weight because the TV takes care of the pin weight. Good Luck
