Rim Width and Offset

[Jhadley4]

I've looked through some of the rim/tire threads already so I figured I would ask. I got a 20 2500 Laramie Crew with the 6.7. Im looking at getting a new set of rims and tires. Ive decided on the 35x12.5R20 tire but I cant seem to find the right info on which rim. I want to get similar to the picture below of the red truck for how aggressive the stance is which is pretty much flush. I have been told by someone that it is a 20x10 with a -18 offset. When I look up the rim online the info says they only make it in a 20x10 -24 or a 20x9 +18. Any input would be appreciated or any other recommendations. I think I would prefer a 9" rim but i'm open to the 10 if it gets me more flush.
Thanks for the help!
The grey one is mine. Was all stock in this pic except I had them smoke/tint my clearance lights which I’m extremely happy about!

Sounds like you want the 9 inch with a +18 offset. I have +12 and the tires sit about an inch outside the fender. That negative offset would be way past your fenders.

Do you have any pics down the side of your truck?

After research and a few phone calls I am going to run 17" x 9" with +20 offset. I will be going 37s with a lift. I would pick the same wheels if I was going 35s though. I don't like my tires sticking out much. CJC Offroad has some videos on wheel fitment.

Chose the 20x8 +18mm. Will post some pics once they come in and are on the truck. Will be paired with Toyo AT3s(35x12.5x20).
