Probably gets asked a lot but I can't find anything in my searches... What's the biggest tire I can fit on my '05 1500 Z71 Crew Cab w/o any serious lift. I'll crank the torsion bars up an inch or two but that as high as I wanna lift it. I'd like to get 305/70/17s on it. Do you guys think thats possible. I'm not affraid to trim the corners of my bumper or air dam a little bit (key phrase... "a little bit").
