What a can of woims just to upgrade your wheels, eh?

I'd just go with the stock studs and avoid even more potential hassles. They are fine if you use the right lug nuts to begin with. I have never heard of anyone having a problem with the studs on any vehicle, UNLESS they used the wrong lug nuts.

 

Dealer gave you the wrong nuts....betcha they are standadrd nuts used on a metric stud!

 

This could very well be it... and now that I think about it, more than likely.
