New Wheels what will fit?

[Showtime250]

I am looking at Black procomp rock crawler wheels. I recently installed a toytec 3inch lift. I went with the spacers in the front and the aals in the rear since I am going more for looks than fucntion since i have 4wheelers and a new rzr to do my offroading with. Anyways after installing the lift my stock 16inch rims and p265 grabber at-2 r about 3/4 inch from rubbing the upper control arm. So i need new rims with my future larger tires. I was told to go with a wheel with 4inch backspacing or less and I will be running either a 32x11.50x15 or a 33x12.50x15. Those wheels come in 3.75 inch backspacing and 2.5 inch backspacing. Witch wheel would help me out more and does the offset have anything to do with it. Thanks for your help guys.
