I just watchedon youtube. I plan on running 37's when I get my JL. Why not keep the stock spare? I'm be off-roading in Maui. Although there's plenty of places to use the Rubicon, none are too far from the pavement. Should I get a flat I'll put the spare on the front and head to town to get the 37 fixed. Most of the pavement home is 35 MPH max, although there is 15 miles of 50 MPH.
