This thread is so very sad.

1. Our X5s don't have lug nuts. They have lug bolts. By definitions, nuts have internal threads.
2. While our X5s all have lug bolts that are loosened by turning them counterclockwise, one can only hope that the OP never works on an older vehicle (ie 60's vintage) that has a combination of LH and RH threaded lugs, on either side of the vehicle. Last vehicle I owned that used LH threads was made in 1997, so you don't even need to go back that far.
3. Use of the words tighty and loosy automatically disqualifies all applicants from the man club. Sorry, it is a bylaw.
