Smallest offset for a 35x12.5 without the tire hitting BTF Upper control arms

[Ryan Rives]

I have a 2002 Ford Explorer xlt with a 3" spacer lift and a 3" body lift, I am wondering what is the MINIMUM offset I need to run 35x12.5s and clear the UCAs. I currently have 35x12.5 tires with -12 offset but I would like to go with a smaller offset to ease the stress off of the wheel bearings and suspension components.

maybe you could try going to a positive offset wheel with spacers and figure out where the sweet spot is at and let us all know
