I'm looking to beef up the look of my 2018 Tahoe LT. I don't want to do a lift on it yet, but want to put new wheels and tires on it. I'm looking at the Black Rhino Rotorua with Duratrac AT's. Question, would the 18inch wheels with 275/65r18 look better/more offroad-ish than the 20inch wheels with 275/55r20? Thoughts on aesthetics of whees/tires and sizes?
