Tucking 18x8's

Wondering if anybody knows if a 18x8" wheel will tuck on a 87 MM?
The wheels I have 2015 Z71 wheels with a 5.5" back spacing and I know I have to bore the centers out but wanted to see if i can find out before I bore them.
If those won't tuck I have some 16x7" Z71 wheels I know will tuck. The plans are to bag and link the rear and bag the front.
Instead of trying to find spindles I will step the control arms 2". Now when I step the control arms I have been playing with the idea of narrowing the arms 1/2" which might help to tuck the wheels if need be.
Thanks

That's +25mm of offset, for an 8" wheel you preferably want 38+ if not more. They may tuck with a little pulling of the fenders. I believe Titan 18's are the same size/offset and people have put them on mighty max's so they will probably fit.

Thanks, I guess for now I'm going to go with the 16x7 wheels.
