[Experianced2]

The wheel nuts on my 2006 Chrysler 300C were impossible to get off today.

They were the rear ones that had not been off for 6 years or so.

I broke a Snap On wrench tying to get the first one off. I view the problem just as some corrosion on the threads.

If I had a flat there is no way I could have changed it on the road. The tire has a slow leak and I found a nail in the tread.

Thus I removed them from all the wheels, oiled them and put them back.
