Hi gang.> What educated guesses do you have on a full size 84 4x4. Im looking to get some rockstars maybe some 18x9 or 18x8's. Im planning on some 31's too. No lift and dont want to look like the rims are ridiculously bowed out.. thanks

 

i know with the stock 15in wheels the back spacing is 4in, if it were any bigger the rim would contact the tie rod. if you want more back spacing (which is the opposite as most people would do) the you need a rim bigg enough to clear the tie rod a minimumof probly 18in wheels maybe 19. but a bigger back spacing will draw the tire into the fender well which you probly dont want unless you going alot wider then stock (15x8)

and the K5's came stock with 31x10.5x15s
