yea that is a bit much...reminds me of a guy I know around here that took a good looking, although ifs, lifted z71 and put 22's on it with some kind of a/t 40's that look like street tires and added lambo doors. My Tahoe may have had 22's on it when I got it, but I still say it looks better than than that...even though I'm still losing the 22's this week. I can imagine the added stress of big tires would be hell on ifs, but the weight of big wheels and tires would be even more it seems....but obviously it never sees more than a gravel road so that lessens the wear a little I imagine...or at least immediate breakage.
