Let me caution you against 20" wheels. I made this mistake when I ordered my 2011 FX4. Thought they looked better than the base 17" wheels, which they did. Then the first time I took it off road and rubbed the shiny clearcoat off of a section of the wheel against a rock it became VERY clear to me why sidewall height is important in off road applications, keeping the damn rim above obstacles that might otherwise damage it.
What ever you choose, I hope you're happy with it.

The bigger the rim the less tire options you have and the tires will always be more expensive.
