So originally thought wheel locks were a joke.
Put on my winter wheels today. Torqued them to 74ft-lbs and on the third wheel one of the pieces sheared off! Looks like it was almost completely rusted through.
I decided to take the others off and I sheared another one! I'll post pics tomorrow. They are very poorly made......I suggest everyone to TAKE THEM OFF!
EDIT: changed 'winter tires' to 'winter wheels'.
