Sorry new to the forum. I have a 2012 jeep wrangler unlimited. I am interested in putting 18" wheels on it with 295/70/18 tires. It currently has 17's with no lift. I am looking at the 18x9 KMC Rockstars. I have read various forums as a visitor about the rockstars and appreciate all the info. As listed in various other threads the wheels are 18x9 with 0 offset, and 5 in backspacing. I know that these will fit the stock jeep but I am planning on putting on a 2.5 lift. Will i still be able to use these wheels once i lift the jeep? Or will i need wheel spacers?
