Back Spacing

[hd04]

I am lifting my 2500hd 6 inches w/315/75 16x10 I dont want my wheels to stick out alot and was wondering would I need a certain back spacing to keep this from happening or would I have to go to a 16x8?

Im gonna guess that you will need at least 5.5" of backspacing to keep most of the tire in. A guy I know has 16.5 x 10's with 4.5" and they are way out there

RCD says not to run anything more then 4.5" of backspacing. That's from my installation manual. The front wheels are going to be kicked out a bit. I'm looking into spacers to compensate in the rear. RCD also says not to use spacers either though Oh well, I'll figure something out eventually.
