I know this is a stupid question but I'll ask it anyway. I have a '96 I6 ZJ with an OME 2" lift (springs and shocks, stock control arms), stock track arms, ARB bumper w/ XD9000, JKS Quicker Disconnects, and haven't installed any bump stop extensions. I'm running stock 225/75-15 rubber (please don't yell at me) but have a spare set of 31 mud terrains I'd like to swap in on 15x8 rims, 4.5" backspacing. With the front end disconnected it'll flex like crazy, how bad and where will my 31" Mud Kings rub? One night I got a slight scuff on the inner fender plastic up top, but to run 31s do I need to install some bump stop extensions to keep them from eating my Jeep?
