i bought a 300sd that had worn out tires on it..

the former owners bought michelins and then never rotated so
the tires were 5 or 10 years old and had not been changed.

i had 2 stuck lug nuts...

i went to mechinic after mechinic for over a month..
maybe two months...i carried the new tire around in the trunk..

I would spray the lug every day with PB something... it was like
wd40..... i would spray it then put duck tape over the hole to hold
the oil in for a little while...

eventually i decided to use a ratched and a breaker bar... and
I broke the ratchet... so then i went a bought a 1/2 inch breaker bar
and the correct socket... and then i was able to get them out..

then we greased the lugs and i take it and have them rotated regularly..
now...
