Okay im a rookie and im not sure about backspacing and all that but i have a 2004 f-1504x4 screw im gona put a leveling kit own it and im gona put 20x10 and 33.12.50 if i order that size will it fit right or what about the backspacing i hear im just gona order that size and should it fit?

 

Yes, it will fit. I'd want at least 5 inches or more of backspacing. Personally, I think a 9 inch wheel with at least 5 inches of backspacing will look better because it won't stick out as far.
