Bidred,
If they're like mine, every other chrome nut cover (the ones with the dimples on them) can be pulled off. They make a cover pull-off tool. It looks like a large pair of pliers with vinyl coating on the ends to grip the cover easier. You can pull them off with your hands by wiggling them a little and pull toward you..After you remove the nut/lug covers there will be keeper nuts that hold the rim cover to the steel wheel/rim
When re-installing make sure you line-up the valve stem...
