285/70/17 are 32.71"x11.22". I'm pretty positive i can't run those, with my moabs. when flexed out my rear tires barely tuck in the fender, and i mean barely. my tires are a lot narrower too 32.06"x10.04". thats over an inch wider, and over half inch taller. not sure on the backspacing difference of the wheels anymore though.
