How do I remove these plastic rims

I have different, but similar wheel covers on my Gen 3. I put on gloves or use a rag to protect my hands and yank hard on a couple of the spokes.
You could try prying the outer edge using a rag covered putty knife but I always chicken out for fear of breaking the plastic outer rim.

 

Never mind. I thought the lug nuts fastened the wheel cover to the wheel.

it's a weird design try putting air in the tire it's a pain

 

Those are nice wheelcovers. I like the style. But wouldn't fit on my 07 wheels.
