Modded's truck does look sick.
It really all depends on whether or not you want them to tuck, sit flush, or don't mind if they stick out a little.
Also remember that rears will appear to sit in a little further due to front track width being wider than the rear track width and that the front end (body) taper in some. If you want to correct this appearance issue you can order different offset wheels or use hub-centric spacers. If using spacers, I recomend ET style lug nuts and possibly longer wheel studs.
With the +45 wheels I am running, I have to run spacers in the rear, otherwise they look funny compared to the front and rub all the time. I am using 15mm hub-centric spacers, longer wheel studs and ET style lug nuts. Just by looking at my set up, I could run +28 before they would stick out in the rear.
