Go to aev's website and look at all their photos. Their wheels are 5.2" backspace and most of the tires you will see them with are 12.5" wide. That will show you how far the stick out with 5.2" compared to the 4 and 4.75" you are looking at. I would go with 4.75. They already stick out some with 5.2 and 4 would add 1.2" more on top of that.
