Bigger vs smaller tires and wheels
Is there any advantage from going to a 20 inch wheel over a 16. Also what's the advantage of going from a 265 to 285 tire in either configuration?

There are tires for 18" and 20" wheels that have higher weight ratings than you can get for a 16" wheel. That is the main benefit, that I can see, for going with the larger diameter wheels.
This is only a concern if you're trying to run a single rear wheel truck at a rear axle weight greater than 7500 lbs. If not, then there really is no reason to change from 16" wheels.
Even going to 18" or 20" wheels, you reach the max rear tire weight rating around 8000 lbs rear axle weight, so there isn't all that much weight carrying benefit (500 lbs) to the larger wheel size, unless you go with 19.5's or 22.5's.
