Hi everyone I am new to this , I have a 2013 unlimited Sahara and I want to upgrade the wheels/ tires... I have been doing some research but I have no idea what backspacing or things like that mean ... I found a set that I like they are ... 20x9 D616 Fuel Contra Black Wheels Rims, 32" AT Tires 5x5 , 1mm offers and 5”back space... I drive an hour everyday each way to work so I don’t really want to lift it I just want to give it a better look with new wheels... does anyone know if these will fit with out other modifications? Thank you!
