So how the heck are oyu supposed to know what tires to put on if you wanna go factory spec? If I have 4.56 would I put 225s or 265?


Since yours is an auto with the 4.56's and you want to keep it is stock spec's, you don't want to go any taller than the 225's(28") tire. With your auto tranny and 4.56's your stock tire package was the 225's. If you upgraded to oem 4.87's you could then run 31's and be within stock spec's. Or, you could convert your rig to a 5spd and then be able to run 31's with the 4.56's, or 33's with the oem 4.87's, etc.


More than tread lightly. Leave it like you were never there, nor anyone else.
