Distance between tire and the front of the wheel opening

[accountant]

I am running 35's with a 3 1/2 inch lift and 1 inch body lift. I am starting some body work on the rear quarters -- molding in old front quarters to the back and taking off my flares. What would you suggest as the minimum distance from the tire to the closest part of the wheel opening? I want to make sure that I have enough distance so my tires do not hit the new section of metal. Thanks. Hopefully this makes sense.
