I was in the exact same boat as you. Wanted a wider stance, 90% looks, 10% for the trails. Bought a set of Cragar V5 rims...right bolt pattern, right inner diameter, and GOOD TO GO. 15x8's make my 235's look MEAN, give the truck a whole new look. that plus the coming lift, and its going to be a cheap and easy modification.
rims were 200$ said and done. they are 39.99 each for black online.
If you want to go this way, let me know, you have to cut about an inch out of the bumper (2 minute job). Then no spacers, and minimal stress on the joints.
