Removing the covers every time is not going to be the fun way to go---but I might shed some light on how?
If it is what I know about(??) there will be a couple of the "nuts" which are meant to be unscrewed, even though most of them are fixed solid.
There are meant to be indents pressed into the metal of the fake nuts as a way to ID which come off to remove the covers.
They are about 1/4 inch long "dents" pressed into the thin metal and can be hard to spot.
A quickie way to spot which may work?
Take something like a screwdriver point and tap each "lugnut" cover and listen for two that sound very much different that the others! Hard enough to make a noise but not hard enough to dent!! Kind of like tapping on solid metal versus hollow metal? None sound really solid but two should sound much more like a " tinnng" than a thump?
When you find one that sounds different, look near the place where the nut and cover meet for the dent. Easy to show, easy to demonstrate, but really weird to write about!
Unscrew like normal if finding the right ones. One should be close to directly across from the other.
WARNING: This is what I have seen, so you might have different, so don't beat the horse too long if it doesn't work!!
EDIT: Tube vid may make more sense! Look at notch at 21 seconds into vid?
