I ran 33s on 16s for a while without a lift. Due to proper backspacing, it didn't rub up front but the tires kissed the rear fenders when articulated; when articulated aggressively, they french-kissed the fenders and popped them off a bit.
Here it is with no lift.
I was also high-centering pretty often and bumping my trailer wiring (breaking it off) on departures. So I finally caved-in and lifted it 2.5".
Here it is lifted.
Sometimes lifting makes sense. Don't do it for cosmetic reasons; don't buy tires for cosmetic reasons. Don't marry a stripper unless you really love her --- same thing...
