I have a 16 MKX and my lugs were trash. I caught a flat while parked at work and tried to replace using the spare. Only issue, the factory lug wrench would not fit the factory lugs on the vehicle. I had to wait for someone with a four way lug wrench to show up which ended up stripping my lugs. I was so frustrated that I just replaced all the lugs on the whole vehicle and kept the wrench since it works with the jack...
