The beaten horse - Dreaded tire sizing, choice, and fitment Q's

[Pain@thepump]

I've searched, and have been reading for the good part of a day, until my occipital lobe began to hurt. I just got back from picking up some wheels for our Z71. They are 20x9.5 +15. I forgot to ask the backspacing.I guess my question is what size tire can I fit w/out any mod? I plan to purchase falken wildpeaks because I've had them on the truck and they've be nothing short of awesome.

So 20x9.5 +15 w/ a 285/50/20 work w/out a leveling kit....? (I do prefer the M/T A/T looking tires over plain street styled tires ) I am open to tires that may have better clearance in different sizes/widths. Minor rubbing I can live with. Any and all help is surely appreciated.

I would think a 285/50/20 would easily work. I believe you can get away with 33'' overall diameter and the 285 is no problem at all. You most likely have a 38mm offset.
