The stock 18's are actually 7 inches wide. Really skinny for a 12.5, it was hard work getting them on there and getting the beads set.

Plus they have a different offset than the 15X8's that we have our MT/R's on. The MT/Rs stick out a little bit, maybe half an inch past the fenders on my rig. These sit pretty much flush with the fenders. I don't know what kind of clearance you have inboard with your new SAS up front.

I also really like those FUEL wheels you posted. One of my favorite wheels is actually the wheels that come on the Toyota Rock Warrior package tundras. They are 17X8.5, +38 offset.
