The width of the tire is not the only consideration, it's the width of the wheel, the tire width and diameter.
Don't buy the hype that you need 3.5" or 4.5" backspacing in every case. When you use less backspacing you begin to rub in other areas and the tires are sticking way out beyond the fenders.
In addition, too little backspacing moves the scrub radius out, wearing tires out faster, helping contribute to DW, and adds extra strain to the unit bearings
