This.
I had to take my 2007 Silverado to the dealer and even they couldn't get if to free up. Ended up cutting it out with a torch.
Now the spare is in the bed.
Yet another crappy GM design.
Not just GM, I almost always carry a floor jack and four way with me just in case. Twice I have tried to help woman in Dodge minivans with flats. One time, it was so rusty, after beating it enough, it came down but it was flat. I had to get to work, so I took her home and happened to catch her after she got the flat fixed. Another time, I came across someone with the same issue. The spare was also flat, they were right near a tire shop so it was fixed faster.
Right. I've heard and seen this on various mfgers.
Probably, cause no one periodically lubes them.
