we have sevaral family owned tire shops so i have done this sevaral times...with stock wheels you can run 315-75R16(35-12.50R16)with a leveling kit but it will hit in hard turns so with the 2" lift it will clear,but with the 315's being as wide as they are it would look better on a 8" or wider wheel verse the stock 7" wheel..hope this helps

you shouldn't have a problem with the 16X8's with the 4.5" backspacing,but to do it right with the 315's you should go with the 9.5" wide wheels...i don't have any pics.. check out my garage for some pics of my truck with 20X10 eagle alloys with 305-50R20(32.8-12.50R20) tires..hopem this info helps http://www.duramaxforum.com/forum/vbpicgallery.php?do=view&g=107

the ones i have are a 4.634" and they are also avalible with a 5.697" but i didn't want them due to the fact it would hang out the side..hope this helps
