which soft 8's?
 

which soft 8's should I get if I were to run 33x12.5x15?

or should I just go with the 16x8 3.5 back spacing? I have a 3" body lift, shackles and spacers and plan to run 33"s

with a 3.5" BS, the wheel will be sticking out of the fenderwell a little, is that the look your going for? You said a 33x12.50x15 tire , that wont fit on a 16x8 wheel. An 8" wide wheel is what you want for a 12.50 tire.

Yeah I changed my mind last second after posting about rim size, Im going to stick with 16"s, yeah I want the 3.5" BS, so I guess what tire I am looking for is a 33x12.50x16 which will fit the 16x8 wheels I want..correct me if I am wrong.

Thanks

yes, if your going to run a 16x8 wheel then you will want a 33x12.50x16 tire, or a 285/75/16 would work as well, just a little shorter and a little narrower at 32.85" tall, and 11.22 inches wide.
