Jeep keeps saying the Rubicon can run 35's with no modifications required. Does that mean we can put 35's on the stock wheels? I know there is some disagreement about if you should put 315/70/r17 BFG's on 7.5" wheels. Sounds like some shops will do it, others won't. But will the back spacing on the stock wheels be sufficient to run a 12.5" tire anyhow? Maybe this is where the wider Rubi axles come into play?
