Trying to compile some info on wheels that will tuck. Here is still a great thread http://www.fullsizechevy.com/forum/general-discussion/exterior-tech/76444-wheel-offset-explained.html

For a NBS 99-07 classic, 4" front spacing is the "magic number". Based on those ^ equations, frontspacing of the wheel only would be....

width offset front space
8.0 +15 3.90945
8.0 +20 3.7126
8.0 +25 3.51575
8.5 +20 3.9626
8.5 +25 3.76575
8.5 +30 3.5689
8.5 +35 3.37205
9.0 +25 4.01575 will not tuck
9.0 +30 3.8191
9.0 +35 3.62205
9.5 +30 4.0689 will not tuck
9.5 +35 3.87205
9.5 +40 3.6752
10.0 +30 4.3189 will not tuck
10.0 +35 4.12205 will not tuck
10.0 +40 3.9252

Please feel free to correct my math, add other wheels sizes and offsets, and other years like obs 88-98 and nnbs 07-present etc...

Not a big fan of tucked look, like my tires sticking out of my fenders! :cool:

Nice list. I have a 4/6 also.

Stock height or level, I'm with you. But. it's tough to do when you have a lowered truck. You have to pull those tires in to have any sidewall at all.
