Factory wheels rusting from the inside

[KBToys]

For the last couple of months pretty much all my tires have been slowly loosing air, when it got really cold here I was needing to add air in them almost every week. So I took them into the tire place to get them checked out. They told me that they are rusting from the inside by the bead. Anybody else have this issue? I was thinking of just sanding them down and prime it.

I've got the slow leak in one of mine as well, guess it's a good reason to tell my wife I need new wheels. LOL
