Well Its abouut time I purchased some new wheels and tires for my 05 Dark Shadow Grey Super crew. I am asking for you help, please show me your wheels and tires with size and type of wheel. I am going to run a 20 inch wheel but I am unsure of the proper back spacing in order to keep the tires in the fenders. Please help me with some Pics. I want to get Nitto Terra Grappler P275/60R/20 which are 32.99" Diameter and just under 11" wide. Thanks for any help you can give me.

 

Stock backspacing is 5.5". Keep it around that and you shouldn't have any problem.

 

Click on "My F150s" in my sig, I have atleast 1 head on pic of my set-up 325/60/18 (33X13) on 18X9 with 5.5" BS. They aren't 20's like you are looking at, but will atleast give you an idea of how much they will stick out past the fenders.

 

Come on guys just show me some pics of your wheels.
