I have a 2016 Ford Edge. I ordered new tires and they didn't change them until I got new nuts because they were so swollen they were afraid they would come loose when installed. I swapped them out and had to hammer the nest in 8 of them. They are 21mm and some I had to hammer with a 22mm head. They are expensive but the quality is better than OEM. I would recommend people to buy these and wait in the spare tire area. If we broke down I would never change 2 tires and I'm a mechanic
