I bought these tires 8 months ago but received and fitted new tires two weeks ago. They are rusting in the corners after only two weeks of use, but I must add a small caveat that I live across the street from the sea. However, this was never a problem with previous nuts. I used them on a 2014 Ford Fusion to replace OEM Ford flare nuts. They will fit, but the tapered part that first contacts the bolt has a slightly different angle/pitch than the Ford Original Nuts.
