18 x 9 wheels -- +12mm or -6mm offset?

I'm looking to get Ultra Mavericks in 18 x 9 (and planning to put P265/70/18 Bridgestone AT Revo 2s on them). These wheels come in a +12mm or a -6mm offset, and wondering if anyone has views on either configuration.

According to this calculator, the +12mm version will extend out about 1.0 inches (25mm) farther than the stock 20" wheels, and the -6mm version will extend out about 1.7 inches (43mm) farther than stock. See screenshots below. I'm wondering if being 1 inch out or 1.7 inches out will make that much of a difference, but am inclined to go with the -6mm offset wheels absent any issues.

I found one post on the forum where PopsSmith put 18x9s with 0 offset, which I think looks great. According to the calculator, the -6mm offset wheel I'm looking at would be about .25 inches out farther. I really hate the look of the stock wheels/tires on the limited, especially from the rear, where the tires look so far inside from the sides of the truck.

Any thoughts? Would be great to know of any issues before dropping the cash on new wheels and tires. Doesn't seem like it will rub or look like a roller skate, but I'd be grateful to know if anyone thinks otherwise.

In anticipation of getting trolled for not searching, I have searched and found helpful posts like this one and this one. I'm posting because not a lot of the posts relate to LTD trucks, and I'm interested in knowing how all of the stupid body work on mine will impact the look of wider/offset wheels.

Thanks in advance.

-6 for sure. You need to worry about the backspacing on a 9. I'm running a 17x9 0 offset and the backspacing is 5". More positive will yield you a bigger BS, neg will have less. If I wasn't using a spacer, it would be real real close to the control arm.

Agree, the +12 will most likely not clear without spacers.
 
I went with 18x9 with 0mm offset with 285's. This puts the bulge of the tire even with the top of the fenders. If I did it over again, I would have went with -12mm, this would put the bulge of the tire, about .5" past fender, but the tread would still be inside. Since your are only doing 265's, definitely go with the -6mm or -12mm.
