wheel covers

I just purchased a set of wheel covers for a 2008 crown vic they don't seem to be on tight is ther a special lug nut for them any help will be welcomed

They do require a special lugnut; this is the same lugnut that is used with the pancake type hub caps. Standard lugnuts will not work.

the set I got was a cheap set I have the pancakes on it now but I have a set of 10 spoke now are ther the same lug nuts or the wheel cover is the problem u have a pic of the lug nuts for them thanks very much

If they're aftermarket wheels, than anything could be up. The wheel covers I was referring to were the factory 17" style full wheel covers.

Do you have a picture of the back side of the wheel cover?

they are plastic
