My 2016 Darts still have all their original lug bolts, none are swollen, and I live in the salt rust belt. I put a layer of grease where the chrome cap meets the actual bolt. All my Neons have their original lugs, none are swollen, and I also use the grease on those. Water creeps between the cap and the bolt, then rusts and swells the cap. Every aftermarket lug I have ever used rusted and looked ugly after two years. I hate having a different socket size. You can find the oem lugs cheaper online, just search the Mopar sites. I have found Dart lugs at the junkyards I visit and have been able to find them not swollen.
