Yes there has been an increase in fuel consumption which I am attributing to the wheel/tyre combo. I also have a 60mm lift which can apparently also lead to an increase in fuel consumption. I'd say stick with 225 or 235 at most. Wider wheels are not always better and can be worse in the wet and dirt roads from what I understand and another reason why I want to go back to 225. My aim is dirt roads, easy fire trails, and beaches, and the highways to get there. No 4WD tracks needing low range.
Yes they aren't the most sexy wheels around but a tyre with a more aggressive tread and a slightly bigger diametre might help the aesthetics much like mine. Of course fuel consumption will be worse ...much like mine lol. At least with a 2.4 engine you spend less on fuel than I do. .
