For the 18's, not much. It's one of those situations where the demand is minimal since most FX's already come with them. So basically whatever the tires and TPMS may be worth is how much you'll get for them. As a comparison, I sold my 2007 18's w/ tires (40-50% tread) and TPMS for $400 just to get rid of them. And it took 2 months to find a buyer.
