If my math & my understanding is correct a 285\70\17 and a 285\75\16 are just about the same width and size in diameter with approx. an extra inch in sidewall on the 16" rim.
All things being equal are there any generalities that can be stated regarding the difference between the two with regard to ride quality and performance?
For example...
Will one have a smoother ride (absorb more shock) than the other?
Track better than the other?
Be steadier in turns than the other?
Allow you to air down further than the other?
Anything else?

For example...
Will one have a smoother ride (absorb more shock) than the other? A tire with a taller sidewall will typically have a better ride than one with a shorter sidewall....if they are the same brand/type/circumfrence. Otherwise, if one has more sidewall plies it will be stiffer and flex less....hence a harsher ride (i.e. BFG AT "C" vs. "E".
Track better than the other? I think that is more dependant on tire width and tread design.
Be steadier in turns than the other? That would again depend on sidewall stiffness and tread design....not neccessarily 16" vs 17" tire.
Allow you to air down further than the other? 16" would have taller sidewalls, hence better for airing down, more flotation, etc...
Anything else? Assuming that the tires are the same circumfrence...16" allows better protection for the wheel rim bead against rocks, more tire choices....I think it looks cooler too IMO...

I was hoping to reuse the 17" black steel oem rims when I retire but it looks like the 17s are more expensive in general than the 16s anyway so the expense of new rims is partially offset by the savings on tires so 16" makes sense to me based on that and the reasons you mention.
