Anyone run after market 18" rims?

Been looking for new shoes for the wife's new silver 4R and am curious if anyone is running 18's? I can't say I've seen anything but limited with them.

The wheel I want only comes in an 18, otherwise I'd just stick with a 17.

 

I was also thinking of going with 18s on my Limited. Seems like a good middle ground (for me, visually) between 17s and 20s.

 

Don't remember the size but this was in my dealer showroom awhile back with 18's.
Rig was nice but dealer is a joke. 50k for a rig with spacer lift ditch lights the rims/rubber

 

Too much rake, wow that thing looks ungainly. Funny how dealers just have no feel for how a truck should be set up. No feel about it all.
