I am trying to remove the tires from the rims on my coupe. The locking device on my rims (picture below) does not look like any thing I can find on the internet. It looks like some sort of cam but I do not want to damage anything by trying to move that cam.
Thanks for any help.
The piece on the right is riveted to the rim. It needs to pivot counterclockwise 90 degrees to release the tab.
