Which offset -12 vs +1?

[TRG]

I've been looking at pics, reading through threads for what seems like months now trying to come up with my upgraded tire/wheel setup...I'm close!  Going from 22x9 rims with +24 offset on 285/45/22 .

 

This is what I want to change to (I currently have a 2.25" leveling kit):

Rims = 18x9  Fuel Maverick

Tires = 275/70/18 (Nitto Ridge or Falken AT3Wildpeak)

 

What I'm really stuck on is the offset.  It's between -12 and +1.  I really like the look of the -12, but live on a dirt road and am thinking about the tire sticking out more and kicking up rocks and dinging up the side panels every time I drive up and down my road...

 

Anyone with a similar setup that can offer any opinions?  Those with the large negative offset are you constantly dinging up the paint whenever you hit the dirt?

 

I'd also be interested  in opinions on the Nitto vs. Falken.

 

Thanks!
