I'm just wondering how i would determine the offset of my rims?? I bought them used and i never really knew but have always wondered. They are 305/55/20's. Rockstars with nittro trail grapplers. They stick out a bit past the fenders. I will post pictures from my phone to show how far they stick out

 

Guess I don't have many pictures other than the one below of how far they stick out ....but ill try to get a fresh one today

 

Thats atleast a 00 offset if not further into the negatives.

 

Ok my guess would be that it's -6 just because I have a buddies who's stick out further & all he has Is a level kit. He doesn't know his offset either though
