Not sure if it matters what tire I use, but I mentioned it just in case. I'm not 100% sure on what wheel I'll end up going with, but it'll either be 9" or 10" wide depending on what will I choose. This will be for my 2006 2500HD 8 lug on 6.5. I'm undecided if I'll be raising the truck up or not, but if I do, the front will be raised by lift spindles and that will push out the front track 3/4" on each side. Now do I choose the backspacing and offset for the truck the way it is (stock) or for the aftermarket spindles? I just wanna make sure I get it right because I don't want the wheels/tires to be sucked in or sticking way out. I want it to be just right. This is a lot of money, so I wanna make sure I get it right the first time. Any help is greatly appreciated. Thanks.
