The chrome wheel simulators are held into place with two nuts, the other 8 nuts are fake and will break off if you try and wrench on them.
Its easy to identify the correct two nuts, look / fell for a small indented line on the nut. (See it in the photo) The two nuts will be across from each other. If you have the tire fill extender hoses, they will be mounted under the removable nuts.
A 1 1/8 socket is all thats needed to remove the two nuts.
When you re-install the wheel simulators, line up the the air fill fitting to the correct hole in the simulator. Then re-install the nuts.
