With a leveling kit, what offset would I need (If any) to fit BFG A/T KO's 305/65R18's on my truck without rubbing?

I've very new at this offset stuff so all the help will be appreciated!

 

I'm asking about the offset on a aftermarket wheel. I think the stock wheel offset is something like +40.

 

There is a thread for this check it out

 

stay close to stock as possible and you will be fine.

 

Are you wanting to keep them tucked or do you mind if they stick out a little? If tucked is what you're after +35mm would work but with 305s it will be close to hitting the upper A-Arm and you'll need to level it. I have +30 with 305 and they stick out about 1/2". I'm trying to find stock fender flares to make it even with the fenderwell.

 

I wouldn't mind if they stuck out a little bit. 1/2" wouldnt bother me. I found a wheel that is 35mm. I'm thinking that would work pretty good after reading this?
