yes, that would be 6.35 inches of backspacing. there is a little added offset in the axle width because of the rotors instead of drum brakes, but it is very minor. To fit the larger tires you will need to cut the wheel Tubs and bed to make room. I have a wood bed so it was really easy for me. I left 48 1/2 inches between tubs so I can still fit a 4 X 8 sheet of plywood. It will rub a little on excessively angled drives and even sometimes when I am utilizing the suspension. a roll bar would probably cure that. to get it to really handle you will probably want one anyway.
