How wide aere your 17" and 18" rims?

I am still trying to decide on rims for my truck. Not sure if I want 17s or 18s. I have the 3" lift so I will be putting some 33's on her. The rims won't be any narrower than 9" because of the tire height, but what about 10" wide I noticed some of the rims I have been looking at don't seem to offer a 9" wide rim. Tire widths have some play, about 2" in either direction so how wide of a tire can we run without sticking out too much and rubbing. backspacing will be no less that 4.25, what offset are yall running? I Hate trying to pick rims I can never imagine them on my truck, even with the Generators showing them on my trucks they never seem to have either my exact rim or truck. Thanks fellas.
