Without lift...you can go about 12 inches wide with 38 inch tires...you will get just a little nubba nubba noise from rubbing at full turn.
I have seen everything on these trucks up to 52 inch tires and anywhere from 15 to 22.5 rims...I think one guy actually got 24's made for his even...but 15, 16, 16.5, 17, 19.5, 20 and 22.5 I know have been done...of course lift may be involved!!
Lord send your Holy Ghost into our hearts and make the desire of our hearts Your Will.
Pro-choice, that's a LIE, babies don't choose to die!!
