I'm interested in a set of 16"x7" Boyd Coddington Timeless 6 wheels to replace my stock heavy steel wheels. I like the Timeless 6 wheel because it's lightweight and it has a clean, simple design. I want the edge of the wheel to be flush with my truck's body. What would be the ideal backspacing to get this result? Any info would be appreciated.

 

My 8" wide wheel with 5" backspacing sits fairly flush, so I would think 4" should sit a 7" wide wheel flush.
