I have a 2007 fx4 f150 I'm wondering if switching from the stock 18" wheels to a 17" wheel will have any negative affects on my truck. 2nd is which wheel would have better aspects as far as strength, backspacing and offset issues between the fuel revolver wheels and the ballistic enigma wheels. Any information helps thanks.

 

No negative effects as far as wheels from 18 vs. 17. More offset can wear things out quicker and AT/MT tires can ride worse and kill mpg. That's about it, Fuel and Ballistic will have the same options as far as wheel sizes and offsets really and AFIK they are built the same so strength isn't an issue.
