Simple tire change on 2002 suburban

Hi everyone,
I just bought a 2002 Chevy Suburban and am having trouble with tire change. I have changed many a tire in my life time and this vehicle wheel stumps me. It did not come with an owners manual so I am in the dark a little. Does the center hub come off to get to the lugnuts or do the plastic lugnut covers come off to reveal the lugnuts? I really do not want to do anything until I find out so I will not damage anything on the wheel. Most vehicles have a slot in back of the center hub to take it off to get to the lugnuts but this hub does not have one.

Thanks, dwkidd70

the plastic lug nuts hold it on, unsrew them.
