I have owned my JK now for four months but still have not found in all of the paperwork and searching of forums how to find out. I am the second owner and I am running 285/75/16's. the tires still have good life however when they are ready for upgrade, I want to go to 35's. I plan on adding a 2.5" inch lift and replacing bumpers. I don't know specifics about what I'm going to go with as I am still in the process of seeing what I need out of it. Any help on finding my ratio though would go a long way in getting what I have now vs where I am going to go. 2011 6sp 2 door sport.
