I have an '05 2wd Z71 and I went with the stock tire size....I got BF Goodrich All Terrains.....very nice tire and came with a 50k mile warranty which is hard to come by with the aggressive tread pattern. If you're wanting give it the mudder look go with those...if you plan on taking it offroad, go with the BFG Mud Terrains....an even more aggressive tread, but you're not gonna get too far with a warranty.
