If you have a car with two piece compression nuts you will find that it is impossible to change a tire on the road, your factory wrench will not fit swollen nuts. After purchasing solid chrome nuts, I found that the factory wrench no longer fits. It's perfect, stowed behind the seat AND comes in its own carry bag, hope I never need it. I drive a Ford F150 but a lot of manufacturers use this two piece stamped nut, what the heck are the engineers thinking?
