I will be installing a Carli leveling kit to help with the clearance. From what I'm told a 5 or 5.5 backspace wheel would be the best for the truck but very few rim makers sell a 5.5 backspacing with the rating for a 1 ton single rear wheel.
Got two questions
1. What backspacings are you running with your 2011-2013 trucks.
2. What is the stock backspacing for the 2011 F-350 stock 18" Aluminum rims?
The stock offset is +40 on 05+ super dutys. Those wheels with a +18 offset would be perfect!
the -12 would clear the inside portion of the wheel, but they would be sticking out so far you will have clearence issues on the outside of the tire. The tire would contact the front bumper and fenders.
if you want to see some of the math behind all of it, I just answered a similar question here 20x9 wheels and 35's on stock truck
Send me a msg if you have any ?'s
