Taller, wider, heavier tire. Yeah, you'll use more gas. But, it also depends on your driving style.
Another option (if you aren't just going for the bro look) is 255/85r16. I can't speak for 285/75r16, but with 255/85r16, I get 17-21mpg (no calculation adjustment for odometer variance). But that is keeping at 65 on the highway without getting too happy with the skinny pedal. The 19+ mpg is usually doing long stretches at 55.
Not the best picture, only one I have right now.

 

I just put on lift little 3inch icons so looks little off is my tires

 

Weight, width and tread pattern will matter more overall height.

A taller tire will actually give you a better final gear ratio for highway driving, so if you do a ton of highway over city, get a skinny, lightweight tire and lightweight wheel and it's taller you may get equal or better gas mileage.


The more aggressive your tread, wider the tire and heavier the wheel/tire the worse your gas mileage as well as acceleration will be. Find your happy medium on the spectrum.
