Thank you all for your replies. I don't think I will be able to get pics tomorrow. But will do my best. I did get back and look. There is one one lug with a dimple on it. However, this one seems like it's part of the wheel cover. When I wiggle it, the cover seems to move with it. A total of 6 of them are like this. There are 2 of them that are opposite each other that are firm and don't wiggle at all. They do not have dimples on them. I have to believe that these are the ones screwed onto the bolts under them.
So, will have to try to get something to undo them. Or perhaps I can find a tire place that has a replacement tire they will come out and mount for us.
Don't know how I can get penetrating oil under there.
Why in the world do they put on something that is so horrible to get off? I don't have them and nobody stole my tires yet. Then again, this is probably why I don't have those things on my wheel covers.
We will figure it out somehow.
Again, thank you all!
