Where do I start as far as making sure I get the correct size tire with the correct ratings? Also, would there be any advantage to changing the wheels? Mine came with standard steel wheels, not the fancy aluminum ones.
Most will start by staying with the same size as OE and try to upgrade load range (C to D, D to E etc) if possible. If you have to go up in size to get a higher load range (235/80/16E to a 235/85/16F) make sure you have room/clearance for the added tire size.
As for the wheels, they are stamped on the back side what load/weight they can support, typically not an issue if they are OE, they have to support the weight of your RV. The area of concern is what psi they are rated for. Heavier load range tires require higher air pressures. Again check the back of the wheel to see what air pressure they are rated for. If they will support the psi required by the tires you want to put on, you're good to go. If they won't, either look at different tires or different wheels.
People will debate what pressures should be used vs weight. I'm sure you will get some of that here, but for safety purposes if your wheel is not rated for the max psi the tire is rated for, the tire should NOT be installed on the wheel.
