When purchasing new tires today, we were informed that we needed to replace the lug nuts as the lug nut wrench no longer fit the top of the nuts. We were told that they often have this problem with Lincolns and some Fords. He said they could "force" the old ones back on, but the next time they would have to be cut off and replaced. We researched this problems and found that others had the same problem. This is not acceptable - especially if out on the road and we get a flat tire. I only wonder if the recent accident when a tire flew off the truck on the freeway and hit another car causing it to flip over was because their lug nuts were "forced" on. This cost us an additional $60 and would have been even more if they would have had to cut the old ones off.

I purchased this vehicle in 2020 and it came with these tires. THREE of the four tires either had a bubble or repeatedly lost air around 28000 miles. These are very unsafe tires and unlikely a road hazard damaged three of the four.
