What happened was that I bought cheap studs at a local store I'd rather not mention. I pressed the studs in properly and made sure twice. When I put the wheel back on, I started to tighten the lugs; but then two of the lugs started spinning with the studs

The studs I had removed from my car were original ones and my hubs still had the knurls/splines to press the new studs in. So, my guess is that the cheap studs were made of inferior metal. Plus, all the spinning of the studs with the lugs stripped the knurls/splines even more. It was a "B!+¢# to remove the wheel;however, I'd rather not elaborate on that as things got really bad. Moral of this unfortunate long a$$ story

is to PREFFERABLY buy OEM studs!!!! Yet, my question remains?
