2.5 lift. 33x12.5x15 with 8" or 10" wheel?

[Campbel45]

Hey guys so I'm looking to get tuff countrys 2.5 lift for my 71 k10. I'm also looking to get goodyear's duratrac 33x12.5x15 wrapped on a modular wheel but I cant decide between the 8" and 10" wheel. I'd like the tires to stick out some but not drastically. I'm worried about rubbing and what offset's I need. And I'd like to know if a 12.5" tire will go on both an 8" and 10". I will only be doing slight to almost no offroading. It will be a daily driver with a nice stance.

Summit has a 2.5", 3.75", 4.75" backspacing for their 8"

They only have 4" backspacing for their 10"

I've searched and searched but I've heard yes's, no's, will only rub etc etc etc. Any help would be appreciated.


This is how I bought it... Does this look stock to you?
