Not saying silver is wrong, he knows his stuff... But if you get tires that are narrow enough you don't need to cut the body mounts, I had 33's on mine with a 3" lift, no rubbing anywhere, that's with the FJ TRD rims... Which I think are 7"... I currently have 32's that again have no rubbing, even with flexing, never tried flexing with 33's to see if they rubbed...
