Rim help needed

I know there been post on rim size but I'm looking to order rims/tires soon and can't spend more hours searching and reading old post. I know everyone says 4.5 inch backspace but what if the rim uses offset. Also what width is good 8.5 or 9, or is 9 inch to wide. I'm looking at xd hoss rims in 17x9 with -12mm offset is that a good size rim and how far out will it stick out. Any help would be great
Thanks Adam

 

Backspace and offset are a relationship. If you have one number you can get the other.
