I had Costco install Michelin Defenders onmy Expy.
The Techs always complained about the lugnuts being swollen when I had rotation done...
So, one time I decided to rotate the tires my self using my 1/2" Impact and 6 pt deepwell impact socket...
I had to fight every lugnut (removal from socket) and I was convinced.
Any hoo, the next time I had Costco do the rotation the tech said they had new stainless lugnuts for
Fords with "swollen" lugnuts.
I said sure, use the new lugnuts.
They haven't swollen so far but they are showing signs of rust
