I am really confused on what lug nuts I need to purchase. I have spent hours searching on here and on the web and I still can't figure out which ones I need. I have a 2012 Ram 1500 crew cab 4X4 sport. I have Fuel Vapor 18X9 -12 offset wheels. Which lug nuts will I need to purchase for these wheels to work? I read some information that the 2012 and the 2013-current threads are different. I am new to all this stuff and never had after market wheels on any of my trucks. I apologize in advance if this has been covered on here but I couldn't come up with a for sure answer after all my searching. THANKS in advance!!
