17s or 16s inch rims?

I want to get new rims and tires but there is so much to think about. I drive 80% intown 20% off road. I dont really want to kill my MPGs but i love the look of bigger set up. I drive a 2009 taco 2wd prerunner and what i had in mind was 5100s adjustables at 1.5 16x8 method wheels on 265/75/16 or 265/70/17s. Any pics and info would be great.. Thanks

 

Running the setup you're talking about with 265/75/16 on some non-aggressive tires and a spacer.

 

Tires were somewhat cheaper when I ran 16's on my Jeep, but I can't remember by how much. You do ,however, have a better selection of particular tires if you go with 17's. I found I was limited to some tires due to the 16's
