Well lets see... The 2015 Ecoboost could be purchased with 19-inch rims sporting 255/40 tires stock so we know the size is not an issue. The 100W is the "Load Index" and "Speed Rating" so that has nothing to do with your issue either. Let me ask you this Austin, are these rims stock Ford Mustang rims, or are they aftermarket? It's very possible if they are aftermarket that the previous owner ordered them with the wrong offset and this is what is causing your issue.
