We just bought a new Jk in may, it's my wife's driver. She has never owned or really driven a 4x4 in the winter. She always has 4 snow tires on whatever she owned. She asked the other day about getting snows and I looked at her in a way Ii guess she thought odd. Do we need snows or are the wranglers that came on it good enough? Look like an all season tread.
